"So cables supported in plastic trunking or in plastic conduit will also
need additional metal clips."

How does that work with conduit?

Is that for cables that could fall across escape routes?

It for all cables in any location now...

Most cables in vertical mini-trunking will just hang close to the wall - and
it'll take longer for the trunking to melt - that on a ceiling is in the
worst place.

As for RCD on lighting circuits: great - get a shock from a mains tool,
lights go off, fall off stepladder!

This is why even on basic installations to share out circuits between
more than one RCD such that you don't kill lighting in the same area as
the sockets etc.

Separate RCDs/RCBOs would be OK, so long
as the whole board doesn't go off.

"whole house" RCDs went out with the 16th edition.

No unprotected sockets: there goes the freezer!

Dedicated RCBO.
