I think it is not handled in the spec (yet).

for outdated or corrupt thumbnails: delete it
if the user requests it (for example, there is no thumbnail of
that size yet), the old thumbnail should stay I think. There is no problem
to have two thumbnails, as long as they are both valid. Think of the
following situation:

2 programs have different default thumbnail sizes. You first use program #1,
it creates a thumbnail. Then you use program #2, it wants a larger
thumbnail, if it would delete the other, program #1 needs to recreate it.

so I think the thumbnail should be deleted if it should be deleted according
to the cleanup rules, else it should not be deleted.
