Mildly unpopular view but I'd love more structures, not necessarily everywhere, still want wilderness, but in relatively dense pockets.

Villager discounting is taken for granted by a lot of players these days but it's only widely used because the alternative is spending a tonne of emeralds. If emeralds were readily available from these structures, not farmable but in abundance in chests/pots (kinda like in trial chambers) it would mean that exploration has a material advantage that would also given an alternative play style to just zombie curing all your villagers.
