Why would it matter whether "dump" or "volutil dump" produces a blob of
data (either full or incremental).

I wouldn't expect that to be feasable, different communication
protocols, very different metadata (AFS doesn't have versionvectors).

Yeah, there is as yet no utility that can pull a single file out of a
volume dump, so there is not much use for file indexing. However, most
accidental file losses are covered by mounting the backup volume under
"OldFiles".

F.i. when /coda/usr/jaharkes is the volume "vmm:u.jaharkes",

    cfs mkm /coda/usr/jaharkes/OldFiles vmm:u.jaharkes.0.backup

The backup volume is 're-cloned' everytime backups are done. So it would
normally contains yesterdays files. This saves a lot of going back to
tape for a single file situations in case of user error.

The case of losing a complete server is either solved by resolving with
other replicas (again no need for tapes), or restore full dumps anyways.
