Fully agree with the generality here, this is namespace squatting after
all. Tile caches though may contain actually data which comes from other
providers (Bing is my primary example).

Nothing against using something more specific though.

I quite like your second proposal, with $XDG_CACHE_HOME/osm/tiles, which
is quite unix-y, and offers a nice namespace for other osm related things.

I would also change the windows and OSX path then, to use a OSM
directory prefix for the same reason. I have no experience on
Windows/Mac, so if anybody has a better suggestion (maybe some other
project is already using a known directory), please let me know.
