kde does, the others, dunno, but imo, doesn't matter. Fact is, any toolkit
*could* implement caching, and the standard mandates that in order for any
caching implementation to work, the timestamp must be updated.

Of course, that's a given.

Wrong, it would (ok, could, depending on imlementation) cause any app
(currently running or not), using any toolkit (that supports the fdo) spec
to not recognize the new icons.
