I agree with Fons here, and I have been bitten by this more than once
myself. Snapshots are often used as a safety measure, and now it is too
easy to accidentily save your changes to a session that was not meant to
change. The fact that the original session, and the snapshots often look
very similar, makes such accidental saves very likely. I agree it is very
flexible that snapshots can be treated as ordinary sessions, and that
shouldn't change. If only there would be an option in ardour (that would
be on by default) that would warn the user that he is saving changes to
a snapshot, and NOT to the original session.
