I raised this like 4 years ago, and at the time, the ability to switch
from SuSE to Red Hat was my biggest gripe. I was on SuSE, and hating
it, and wanted to migrate to Red Hat.
Surprisingly, Red Hat didn't seem to care.
We bit the bullet and did it the hard way, so that's no longer a big
issue for us, but I have to imagine it's a good strategic point for SuSE
- they can achieve vendor lock-in simply because Red Hat won't even
offer an unsupported XFS migration path.
These days, though, your #3 and #4 points (dynamic inodes and 8TB limit)
are huge for us.
Red Hat may very well lose our money as a result, too.

the way back to RHES 2....
I would like to see the inclusion of other file systems because of four
main reasons:
1) speed (other file systems are faster at what we do)
2) fsck takes WAY too long on ext2/3 file systems
3) dynamic INODES (A big one)
4) 8TB limit is too small and GFS overhead is way too high
For this reason, we now have to support two versions of Linux in our
shop and RH and is missing out on our licensing fees for these others.
Our RH number are shrinking, but Linux use is increasing and it all due
to this very issue.

One argument for a filesystem other than ext2/3 is that those have an
8TB limit. There are currently raid arrays on the market that have a
12TB capacity.
I suppose the RedHat response would be to run GFS? But we only have
one server, not a cluster. And it seems overly-complex considering
the existence of XFS.
XFS has other advantages too:
- it's supported by other distros, so there's no vendor lock-in
There is especially no vendor lock-in with ext{2,3,4}, and someone
from RH has already stated RH doesn't wish to acquire the resources
(people) to support other filesystems, a position I understand well
enough.
If you have a need for larger-than-8 Tb filesystems, express it via
your Red Hat support contact.
