We're not going to drop them. See below.

It was not my decision, some people here had been asking for this
change for years and some of the code supporting this had been
written before I became a mere developer.  We're just trying to
accomplish the work.

(As for me, I had always the feel that Scheme is TRT here. Look,
e.g., at Guix and/or Kicad.  The latter uses sexps for its file
format and a parser for it written in C++ :-) It's a shame that
geda moved other way around having all means and whose interpreter
just _reads_ sexps natively.)

Anyways, nothing prevents us from reading new config files using
Scheme, and lepton-netlist can confirm this :-) We can do more,
i.e. support sxml config files, json (see, e.g. the guile-json
project) and many more formats.  The concrete issue I'm raising
here is about the ini-file-like config file format that had been
chosen over a decade ago, and I'm going to finish the work on it
anyway.

And anyway, RC files will continue to exist, since smart people
like more automation, eh? ;-)
