Maybe a new `make-nearby-temp-file` would work, where Emacs would try to
create the temp file "as close as possible" to some target directory.

This could also be used for things like "save into a temp file and then
rename that file to the actual destination".

This said, there are some non-trivial security issues at stake here:
make-temp-file should usually only be used in directories which are
either only writable by "trusted" users (i.e. only by the current user),
or which have the magical "sticky" bit set.  So using just any writable
"nearby" directory is generally unsafe.
