There is this changeset: http://www.openstreetmap.org/browse/changeset/9316222 by Komяpa.
I hope he will answer here what that changeset was fixing (so that we know not to worry because some problems are solved or become angry for breaking things).
Answer (through osm inbox) was:
I'm maintaining rendering of OpenStreetMap on maps.kosmosnimki.ru. We're using completely different stylesheet, that shows, for example names for roads on lower zoom levels, names of lakes etc.
Latvia was looking really ugly there, because of refs for roads being in name= tag, lots of name=. and name=ezers lakes.
I pinged user Richlv on IRC, sent him a dump produced by my script (https://github.com/Komzpa/fuzzy-osm), and for a couple of weeks we were reviewing mistakes and strange behaviors (local-language specific - script was originally Russian-only) in it.
After that, I risked to upload a couple of changesets:
* created_by tag clean-up, to make further review easier;
* drop of area=yes tag on forests, for same reason;
* moved refs from name on major highways;
* commited capitalization and all other minor fixes of tagging.
I currently do not plan to do other large automated edits on LV territory, except if I'll be asked.
