Third machine and P flag is there on regular file:

# LC_ALL=C xfs_io -c stat /home/somefile.txt
fd.path = "/home/somefile.txt"
fd.flags = non-sync,non-direct,read-write
stat.ino = 2169031643
stat.type = regular file
stat.size = 4934
stat.blocks = 16
fsxattr.xflags = 0x200 [--------P-----]
fsxattr.projid = 45039
fsxattr.extsize = 0
fsxattr.nextents = 1
fsxattr.naextents = 0
dioattr.mem = 0x200
dioattr.miniosz = 512
dioattr.maxiosz = 2147483136

Seems to be it.

xfs_quota probably needs a fix to don't do that then when in recursive mode.
