Yeah, I wrote code to adapt the 4.4 dump/restore to that filesystem
once.  The changes struck me as gratuitous and stupid.  That Apple
stuck with them seems to me to be...well, stupider still.

I don't think Apple picked up any of the 4.4 FFS changes, nor the fixes
to default geometry parameters to correspond with modern disks, etc --
then they decided based on some fairly elementary testing that HFS+ is
"faster".  Hopefully at some point they will have the engineering sense
to revisit that series of decisions.
