There is one advantage.

Only downside I can think of is its aesthetics - not pretty, but robust and functional.
Perhaps you misunderstood my previous post. The fuse in a British plugtop HAS to be there due to the design of the ring circuit. It's a NECESSARY feature for the protection of the appliance cable connected to it.Having a local fuse to a single socket outlet is a great advantage and safety feature.
Not "taking the whole lot down" is a good reason for using local fuse downsizing. But this is a very different reason from the primary reason British plugs have fuses... without them circuit safety would be compromised. They are a necessity, not an option.He said he bought a whole bunch of UK plugs,.... If one piece of equipment was at fault, it never took the lot down.
I would assume his portable film equipment was all radial. The fused 3-pin was to accommodate rings for sure - and to offer other safety spin-offs which were all thought out, not incidental.Not "taking the whole lot down" is a good reason for using local fuse downsizing. But this is a very different reason from the primary reason British plugs have fuses... without them circuit safety would be compromised. They are a necessity, not an option.
I would suggest to the American in question that he try using more radial circuits.
That is why they are not as safe as British systems.This extra safety feature is generally not a requirement on European 16 amp radials
You need to think it all through.I've a flightcase full of global anything to anything adaptors, and there's good and bad in each one. We're stuck with a fused plug due to the RFC, and we're stuck with the RFC as a left over from scarcer times. Apart from the guarded outlets in the sockets there's little to be gained by our design - over engineered and cumbersome. The Australian one is pretty good.

Say what?!You need to think it all through.
That’s what I said…. Except, thanks to Esther Ranson the end user should never need to know about termination and cord grips anywayThe whole shutter design and the design of the contacts in the UK plug and slcket is very good. The cord grip of the plug works well, and there is plenty of room for termination.
As I say, I think it's the best of the lot.

But the instructions say consult an electrician, who deemed it should be cut off, so all is well.Ooh careful, we'll be entering into the whole 'you can't cut plugs of cos it voids the warranty' thing!
And can I just say the word 'plugtop'. Ta.

Plugtop? What a silly term.
In the late 1980s there was talk of a standard Euro plug that would all adopt.
The problem is that if we wanted safety all over the EU, they would have to adopt the British/Irish/Cypriot 13A-fuse-in-the-plug approach. The UK inserting a fuseless plug on the millions of rings in the UK spells many fires and deaths.This was IEC 60906. It is a good, compact design of 16A plug that follows from European practice with certain incremental improvements locked in, similar in layout to the Swiss SEV1011 which is based on the usual 4.8mm on 19mm centres but with an offset earth pin.
IEC 60906-1 was taken up by Brazil and SA, but failed in Europe. There was insufficient commercial benefit to standardisation, not least because a significant proportion of low-load class II items come fitted with 2.5A Europlugs which are already pan-EU compatible.
I was a keen teenage inventor at the time and I had a go at solving the remaning compatibility problems for 60906 for the UK. The elephant in our particular room is the lack of OCPD required for backward compatibility with 32A circuits. This I solved with value-added features by replacing the socket switches with MCBs. The socket itself is small enough that a UK back-box has space for a version including the MCB(s). The MCB was also interlocked with the plug so that it would only switch on with a plug inserted, and I had a version that would set the thermal trip current according to the shape of the plug. Insert a Europlug or 3-pin plug with a keyway, and the breaker would set to a lower value than with the full size 16A plug inserted.
It worked, but at the time it was too expensive and no-one wanted to take it on. But FWIW the MCB-equipped socket is available from Bticino in CEI 23-50 form. Today I think it would be cost-effective but there's not the interest in 60906 that was buzzing then.
