I haven't read the whole thread Andy, but I doubt theres anyone who has agreed with the Code 2's.
I agree with you and dont think there should be any code for the 3 things you have mentioned.
BS3036 fuses are still in BS7671 so as long as they meet Zs times then they are fine.
As for the 6mm bonding and 10mm ME, have a look at the Best Practice Guide 6 (page 5, section 6.1 notes 2&3) It states the following:
2. A 6 mm2 or 10 mm2 earthing conductor used with an
associated line conductor of 25 mm2 could be considered
adequate if the requirements of Regulation 543.1.3 are met.
3. A 6 mm2 main protective bonding conductor size could be
deemed adequate where the minimum size required by
Regulation 544.1.1 of BS 7671 is 10 mm2, if the bonding
conductors have been in place for a significant time and show
no signs of thermal damage.
