that last post was prompted by finding out about the lego 2L lightsaber hilt piece used in some star wars large figures from 2015-18 (wow i didn't realize the sequels are that old now) and just thinking... lego should do "decorative variants" of more things, especially technic functional pieces.
1x2 bricks have a whole bunch, why not other things?
bushes and half-bushes, connectors, the """1x1 liftarm""" spacer piece
just to add some greebling to functional builds. i just think they're neat
