I'm fine with the idea, but it would be nice if existing systems

over without asking,

Any creative idea how to do that with zypper dup?

I don't know whether RPM supports that but Debian's debconf would allow to
create a prompt to ask the user with the current setting as default.

Does RPM have similar mechanisms?

so that there is no unexpected loss of data - I do happen to
have dumped some stuff into /tmp that I still need and I assume other
users might have
done the same. Better be safe than sorry.

There would be no data loss. As Richard explained, no change on upgrade
for btrfs systems that use the current defaults (tmp mounted from
subvolume via fstab). Systems not using btrfs would get a tmpfs mount on
top of the existing /tmp. So the content would still be there, just not
visible. Which might be problem of it's own but regaining access should
be as easy as "systemctl mask tmp.mount".

OK, sounds reasonable to me.
