The State of Mesecon Stickyblocks

for as long as i can remember, stickyblocks have been in an unstable, creative only state, due to numerous bugs.

as far as i can tell, nearly all of these bugs have been fixed in PRs¹ that are yet to be merged, some of them sitting for over a year.

does anyone know if there will be any progress on this?
