Can we discuss this with a few objectives ? Like define "backup" and
then describe mechanisms that may achieve one? Or a really big
question that I guess I have to ask, do we even care anymore?

Personally I think you would benefit from some slightly different terms.
I would differentiate between backups and archives. Here I am trying to
move away from tape based backups. We do backups to a disk based system.
There is no technical reason why this couldn't be done with zfs send | zfs
receive.
Then there are archives. I am exceptionally fortunate that my group don't
really have to deal with these. If I did then, despite the significant
drop in price for hard drive based storage, I'd still go for a tape based
system. I don't know of anyway to do this usefully under zfs.
I don't believe that there are any good/useful solutions which are free
that will store both the data and all the potential meta-data in the
filesystem in a recoverable way. I've never been impressed enough with
any of the commercial solutions, and certainly not enough to give someone
money for them.
