I planned on flush wall mounting Klik 6A sockets - lights, smoke/heat,
em-light.

Ceiling Rose KLIK will not seal against a conduit box (they wobble),
requiring either a deeper sunk box using plaster as the mating surface
or a surface mount pattress. AX KLIK however are a 1G faceplate so fit
standard backboxes.

It just occurred to me that Klik lacks shuttered pins - so industrial/
commercial only?

I choose to deliberately ignore in this case (the rule predates
Klik). It's quite difficult to make contact by sticking something
in the slots - it has to be very pointed and thin, or a bare
wire.

I use these for kitchen lighting where the lights are attached
to the kitchen wall units, and you run a flex back to a Klik
wall plate, but you don't expect to be frequently plugging and
unplugging them (e.g. only if you are taking down the kitchen
units). You can pre-wire the cupboards before putting them up,
and then simply plug them in. The outlets are on the walls
just above and just below the wall units. I always switch the
above outlets (general lighting) separately from the below
outlets (task lighting).

Table lamp BS546 sockets DO have shuttered sockets conversely - so
domestic legal.

Yes, they are if shuttered. (BS546 does not require them to
be shuttered though, so you may find unshuttered ones too.)
I have used 2 Amp BS546 for table lights switched from the
door in my living room. These feel more natural for lights
which people might move around, where the release mechanism
of the klik plugs is going to be unfamiliar to many.
