Where the upgrade to the new format is done by dpkg, we could add
downgrade scripts as well as upgrade scripts. As for new files, users
already have to deal with different file formats (I.e. what if someone
emails them a file from a newer/older version of Ubuntu), it may be
wise to manually save the new files back in the old format before
doing the downgrade. If gumptacular automatically upgrades
~/.gumptacular to a new incompatible format then gumptacular is broken
and needs to be fixed (consider, for example, if you login to you
account from both the SunOS lab and a Linux lab each with their own
incompatible  versions of gumptacular - you will have much worse
problems with gumptacular than an occasional downgrade would cause).

In general though I think it would be better to allow the user to
install both the experimental and the stable version side by side,
though this may make the packaging more complicated again.
