my first proposal (for parking spaces) reached the voting phase now: osm.wiki/Proposed_features/parking

besides that i have started another one for recycling centres, so there is a way to differentiate between recycling containers and bigger facilities:
osm.wiki/Proposed_features/recycling_centre

and there is also a third one for automated tasks, but it's still only a draft:
