You'd need to make genbki.pl smarter regarding the way to associate
those variables with the defined variables, greatly increasing the
amount of work it is doing as well as its maintenance (see for PGUID
handling for example). I am not saying that this is undoable, just
that the complexity may not be worth the potential readability gains.
