Ecuador: cleaning up an address mess

There's quite a tagging mess here, mostly due to people not thinking about what a name is: https://forum.openstreetmap.org/viewtopic.php?id=69184 I culled a few obviously nonsensical names such as "solar vacio" ("empty lot") already but for the rest I'd like to hear what others think.

The V-something "names" seem to be actual house numbers while most of these buildings are tagged with addr:housenumber being "MZ-something" for "manzana", block. So I guess the possibilities are a) always use the combination of manzana and number as addr:housenumber=MZx n b) addr:block=m without the MZ prefix, addr:housenumber=n, probably best without the V c) addr:place instead of addr:block - I understand the block number is supposed to be used instead of addr:street while the manzana isn't useful without a street. I'm leaning towards b).

Orthogonal to that: would a building name like "Condominio Geminis" go into "name" or addr:housename? The latter is not considered mutually exclusive with addr:housenumber, is it?

Then again, is it worth cleaning that up in the first place, considering many of those "buildings" don't correspond to real-world buildings but rather to something like lots? Maybe deleting the building=* where the subjective difference between the building outline and mapped area is too big?
