Hello. There is no discussion or documentation for this edit as I don't think it's necessary. I just found some values for house=* on taginfo that had an obviously equivalent and documented value. I downloaded them with an overpass query in JOSM, reviewed several chosen at random, and mass-retagged them.

Thank you for pointing out the mistagged nodes. I should have checked the nodes more carefully but didn't think about it. Someone has already fixed them but I'm planning on searching for and fixing similar errors.
