grub2 can't boot new xfs CRC-capable disk format

This format is still WIP upstream, but we should probably have the issue on the RHEL7 radar since we plan to default to XFS even for /boot.
A simple workaround would be to not enable CRCs for the root fs; this may be done by default in any case.
So this bug may be a WONTFIX or NOTABUG, but I figured we should at least log the issue.
We probably do want this support in though - I can imagine we might not always need a broken out /boot?
At the very least can we get a pointer here to some details about the FS feature?
on-disk format stuff has recently been coalesced into libxfs/xfs_format.h
Other than that, we maybe need to do some buddy coding to do this, as I don't think either grub2 or xfs has great up-to-date documentation...
For starters I assume grub2 could just grok new formats, but skip the actual CRC verification... things haven't changed *that* much.

*** Bug 1220844 has been marked as a duplicate of this bug. ***
I have tested grub2-2.02-0.23.fc23.x86_64 installed on an Fedora 21
I succeeded in booting a CentOS 7 with XFS from the fedora boot menu,
but I still cannot boot a SLED 12 with XFS from the fedora boot menu.
Using my openSUSE 13.2 I can boot CentOS 7 and SLED 12.
If you need more information, please advise me, how to create a log from grub2.
