That's great.  Does the same sort of thing apply to file permissions?  If so, I
can mangle owners, groups, and permissions as badly as I want and they'll still
be perfectly preserved when I restore?

Any writing to the mirror other than by rdiff-backup itself is highly
discouraged, but all of the metadata (ownership, permissions, ACLs, ...)
is stored separately from the mirror and should restore correctly. All
bets are off, though, if you add, delete, or change the contents of any
file there.
