They are not useless, they keep thumbnail display times reasonable.
I have used programs that generate thumbnails on the fly, per session
and it is slow and annoying.

They are needed to keep display times reasonable. All programs
should use the same cache, and many do. If you have a favorite
program that does not use ~/.thumbnails, you should probably
file a bug.

well, there are some basic suggestions in the spec for deleting:
There are plenty of ways that a thumbnail could avoid deletion
with these rough guidelines. However, I am not that worried about
it. Disk space is abundant and cheap, and I can always delete it,
or set a cron job to delete every so often.
