Yup - I would only use it if you really are doing a copy and not a
move (neglecting the fact that the implementation of a
cross-filesystem move does a copy first).  I imagine many ebuilds do
copy operations internally, but probably not to an extent where it
would make much difference.  I'm not sure how doins/dobin/etc are
implemented - I think they're copies and so allowing for the fact that
not everybody uses a tmpfs it might make sense to fix those.
