That's just the problem I always have with junction boxes. Not so much
I can't get the job done, but I do find having fewer wires per screw
raises my confidence that they're all house squarely and tightly.

There was a box in the MK catalogue (maybe a standard any brand item?)
with (IIRC) 3-blocks of quad way connectors which is a close-ish match
to what I see as the ideal. It looks like there's space in there for a
single choc-block element for the earth, or maybe joining the switched
live to the actual lamp.

My search continues...
