Is there anything in ~/.cache that is not really cache?

My machine has lots of memory, so I moved ~/.cache/google-chrome into /tmp, which is a tmpfs RAM disk. This makes the browser run faster and reduces SSD usage. When I reboot, it all goes away, but it gets recreated again. All is fine.

In theory, I could move all of ~/.cache there too.

But in practice, how likely is it that some packages (ab)use ~/.cache for something other than temporary reproducible data?

UPDATE:

I decided to try it out and did this:

$ mv ~/.cache ~/.cache.old
$ ln  -s  /tmp/home/ray/.cache  ~/.

and then added this to my ~/.profile:

mkdir  -p  /tmp/home/ray/.cache

and so far everything is working okay across reboots. Removing .cache.old will free up about 2G of mostly ancient files.

If I ever do run into any packages that misuse .cache, I can teach .profile to add a symlink back to a real directory for that specific case.
