By default nothing happens - as I said, the feature is mainly there
for hobbyists.

I don't think this is a good idea because interrupting the user with
highly technical questions like that never really works. So that's not
going to work. There's also the problem that distros typically require
admin authentication in order to modify things like /etc/fstab.

I think the only workable solution is that the user interface simply
doesn't expose whether a device with mountable filesystem is actually
mounted or not - some sort of clever mount-on-demand thing.
Unfortunately POSIX doesn't really make this easy but it could be made
to work by using either autofs (same way systemd does it) or through
clever use of GIO/GVfs.
