I've been keeping tabs on that as well, long time Fedora user here. I wish I could tell you! Usually this implies some sort of lacking stability; yet I don't recall any specific warnings when I was researching opting in. There may be some insights on the upstream XFS/Red Hat mailing lists (most of the developers are there, IIRC) I've replaced all of my old XFS filesystems to address this and haven't noticed any problems... but filesystem things can be subtle.
