So there's no code of practice that specifies exactly how the back-box
earth should be connected?

Correct, because as was stated in the first reply there is normally no
requirement to earth the back box.

which is how you get a nice shock off the screws used to connect the
front plate to the back box.

Are you serious?

With the caveat of there being at least one fixed lug, he's right.
Accessories usually have earthed metal rings in the screwholes.

Personally I do run a fly to the backbox even though it isn't strictly
necessary in my case, because it takes about 30 seconds extra effort.
