For the base fonts I agree this makes sense, but for top level fonts (i.e.,
the ones which TeX/Omega actually works with) it is mainly a nuisance. It
also goes against much of the philosophy in LaTeX as you end up with for
each character separately specifying what it should look like rather than
what it logically is.

Now I don't understand. Are you saying that there is an OCP, but that it
never changes anything?
