If discrimination against N-E faults is required, why are single pole RCBOs sold? There's something I'm not clear on yet here.

Well it's only a problem as you have a TT supply with a RCD main switch.

I've also been reading about the 18th edition, such as it is so far. Fixing of cables in escape routes has come up. I presume the usual plastic cable clips will no longer be permissible, are we going to go back to metal buckle clips? Is their lack of insulation ok today?

There use is fine. If using trunking there are special clips that fit
inside the trunking.
