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...
