Nothing precludes it. The point is that introducing major format changes inline in this manner just complicates the code progressively to the point where your directory walking, inode block walking, and other code winds up being 

	if (new)

	else

_anyway_, at which point it is essentially multiple independent filesystems. I guarantee this won't be the last fundamental fs metadata design change people will want to make...
