Right, I wrote them when virDomainBackupBegin() and friends were not
there yet :-). I see that the newer API is mentioned in the "internals"
doc here, which outlines how libvirt implements incremental backups and
some "pseudo algorithms" on external snapshots:

Yep, I'll mention and link to it. But also I think a separate, use-case
drive doc for virDomainBackupBegin() and friends can also be very handy.
I'll make that a TODO after I clean-up these two first.
