Good point.

But currently typo3temp is mostly used as a "cache". Which is why most
people just regularly "clean it up", expecting stuff there to be
regenerated when required (which is how a cache works).

Core generates very little "temporary files". I can spot:

- t3lib_div::upload_to_tempfile
- t3lib_svbase even has a mechanism for services to "register temp
files" which are deleted on reset()

maybe others. There is typo3temp/temp/ which might be a candidate for
those really "temporary" actions.

So I would also see typo3temp/ as our current spot to place the
auto-generated sprites.
