So I think the 'more tags the better!' belief is very much bogus, at
least for the common case.

Well, that's one theory.

Numbers talk, theory spinning walks

Both Andrew and I did latency numbers for even small depths of tagging,
and the result was not pretty. Sure this is just your regular plaino
SCSI drives, however that's also what I care most about. People with
big-ass hardware tend to find a way to tweak them as well, I'd like the
typical systems to run fine out of the box though.

Fair enough.
