UK Shower switches burning

Maybe because more attention is given to tightening the L conductor.

Do you think that really seems likely?

There doesn't seem to be any reason why it should happen

I think that some people take a bit more care with the L.

I don't doubt that, but can't imagine it explaining such a high percentage of apparent issues on neutral side.

Maybe reversing polarity on the shower circuit would stop it

That's a question I'd love to see answered with something better than speculation.

Doesn't seem any logical explanation. Contacts make simultaneously, give or take ? and current alternates

I'd expect one or two of the boffins round here to have stepped in if there was a viable theory

As @nicebutdim states when terminating cables into terminals they will relaxe after a minute so you need to revisit and nip them up a few times.

Oh definitely, the amount of tails that I come across in consumer units barely nipped up is staggering, I always tighten them, wait a minute, give them a bit of a wiggle any you usually find you get another complete turn of the screw fairly easily.
