There's no logic for generating alternative names in case of
conflict. But I mean, what are the by-label names good for if you
don't know what they point to?

The fix for non-unique labels is not making them magically unique in
non-deterministic ways but by changing them in the first place on disk
or not using htem at all (and uisng uuids or such)
