Generally the salvager in MR-AFS can recreate lost directories filling them with
entries lost+found.<vnode>.<uniquifier>. This is bettter than nothing.
However, if the root directory is lost for some reason that doesn't work.
There was two or three months ago a case on this list where someone
had lost the root directory. I could help him by creating a new empty volume
and then restoring incrementally a dump of his broken volume into this new one.
The new volume had an empty root directory, of course. Now the
MR-AFS salvager was able to reconnect the whole tree.
The user only had to rename the lost+found entries in the root directory
to the original ones.

I know I'm forgetting, but, what cases does it lose in other than "you trashed the root vnode of the volume"?
That may or may not have been the problem, I'm not familiar enough with AFS internals to remember if that's what I ran into.
Ok. Well, if there's code in MRAFS to fix that, well, I'd love to have it, but, life's hard.
