One person's feature request is another person's bug for missing
functionality, so you mailed the correct place.

Umm, how do you propose to do that?  Child processes cannot modify the
environment of the parent.  The only way to invoke mktemp is by spawning
a child process - but that means that there is no way for mktemp to
modify a predefined environment variable.  That is, unless you are
proposing to add a new shell builtin (so that a child process is not
spawned), but then your patch would need to be against the shell (we
don't maintain the shell here in coreutils).

You are welcome to try and write a patch, but it sounds fundamentally
futile based on how environment variables work.  As such, I'm going to
close this request as not a bug, but feel free to continue replying on
this thread if you have more questions or comments.
