If you mean that it writes the history, then that's a usual shell
thing, so that's OK. BTW, that's probably one of the reasons why
"su" redefines HOME to the target user home directory by default.
I suppose that caches could be OK too as long as they are written
in a "safe" place.

Perhaps.
But, for instance, writing a default .emacs would not be OK and would
require at least user confirmation.

So, perhaps this should be on a case by case basis. I don't know about
dconf, but in that case, this doesn't seem to be correct. And if not
writing under $HOME, I think that the owner of the directory should be
checked in some cases.
