What advantage does that have? I see none.

You shouldn=92t be insulted. It=92s like TeX: you don=92t touch the =
core, you put everything in style files. Geda-gaf isn=92t *that* well =
engineered, but it=92s pretty good: the burden of necessity of change =
should be high. =93If it ain=92t broke, don=92t fix it=94 is just good =
engineering.

Despite Peter Brett=92s great work, we simply don=92t have the tests =
necessary to insure that changes to the core don=92t affect somebody=92s =
flow. Geda-gaf can do all sorts of things (even generate makefiles ;-). =
Can you guarantee that you won=92t disturb this? I absolutely don=92t =
want a tool paralyzed by the interactions of added features.

I recall an attempt by a core developer to make SPICE netlisting better =
that broke slotting for layout. He shouldn=92t have put a SPICE-specific =
feature in the core: there were better ways to solve the problem. I =
would hope that our more mature project wouldn=92t release a blunder =
that bad, but more subtle problems cannot be excluded.

But the burden I=92d lay on you is to show that this *needs* to be in =
the core. If not, it doesn=92t belong there.
