I was about to make a report about this too.

Tested in a Soul Sand Valley fortress:

Creating a large Nether Brick spawning platform on a crossroad in the fortress resulted in no spawns after ~1 minute in 20w21a but downgrading the world to 20w20b fixed the issue

Thanks for the comment i am relieved to know I'm not alone with this matter.

Confirmed for Basalt Deltas

Blaze spawners also don't work

Ok, this seems to be a duplicate of MC-184740after doing a bit of backtracking in the tracker. The issue is a problem with the new structure names.
