Great proposal! I was going to suggest something very similar, but I did
not dare because of the number of requests I made.

I have thought about that, too. The upside would be that duplicity would
only need to be invoked once / in one way for a fully blown
low-administration regular backup job. The downside is that it feels
strange that a "create backup" command would have an option to remove
backups.

One thing to consider in this context is if and which options could be
externalized to a configuration file (e.g. /etc/defaults/duplicity) or
an env variable. I'd really like to configure my backend only once, not
needing to type it again and again for each invocation. Other options
that spring to mind is encryption key handling, includes/excludes and
filename format related options (as long as this is still needed/supported).
