What do you mean by this, exactly?  When Dave outlined the requirements
for PMEM_IMMUTABLE, it was very clear that metadata updates would not be
possible.  And would you really cosider this a barrier to marking dax
fully supported?  I wouldn't.

Can you be more specific?  We have ltp and xfstests.  If you have some
mkfs/mount options that you think should be tested, speak up.  Beyond
that, if it passes ./check -g auto and ltp, are we good?
