I could just bung two wires in one connector

Do this one. You worry too much!

Plenty of room for two 1mmsq wires in the one hole. Leave the outer holes
for the pendant flex, as the route for the strain relief is designed to
work best that way (you see those funny little "wings" towards the outside
of the rose? you're supposed to run the blue & brown wires of the flex
through those, so that the wires wrapping nearly 180degrees around them
take the weight of the lampshade etc., leaving the screwed electrical
connections without any force trying to pull the wires out over the next
5-10 years ;-)
