The disk space is not the issue, I think, not nowadays.  I believe the
issue is the _number_ of files in the trash: if there are an awful lot
of them, they make looking for those "precious" mistakenly deleted
files harder.  Or at least this is my understanding; I don't use
trash, so have no experience of my own to share.
