We could ... but right at the moment I'm thinking this would solve 80%
of the problem with about 1% of the work needed for the varlena change.
So my thought is to do this for 8.3 and then wait a couple releases to
see if the more extensive hack is really needed.  Even if we did
eventually install variable-sized varlena headers, this layout would
still be useful for types like inet/cidr.
