Well, not quite.  A 4.4 filesystem was not quite compatible with an old
OS.  (This is important.)

Only if it also stops supporting old filesystems, which so far there
has been no hint of.  I find incompatabilities between even the old
filesystem format on NetBSD and SunOS (3.5) already, though each one's
fsck is mostly able to fix a filesystem from the other.
