Live wire to neutral terminal and vice-versa (not that a bulb cares)

;-)

Earth wire not connected to earth terminal

Would that typically come in from the right (against the raised bit)
and be wrapped clockwise, or just tucked under the same if the flex
was fitted with a ferrule?

No grommet where T&E passes through metal knockout

I don't think that is a 'knockout' as such is it as it looks like it
has a rolled or rounded edge. If it does have a formed edge, does it
still have to have a grommet (genuine question)?

given how much slack T&E there is, the chock-block and 3" of wire (not
even flex) is quite pointless

I'd agree with that as well.
