You are overlooking the built-in extensibility of the APRS
spec.  It provided for plenty of free-field bytes in most
formats so that added features could be added.  It
is in those free fields that we were able to add the
extra 1 foot precison that was requested.  And while
we were at it, we added the datum as well.

Just about anything that has been requested or
proposed can be done within the existing spec.
We just need to all agree on how we do it so
that everything still works.

de Wb4APR, Bob
