Is there a list-serve dedicated to Racket or Scheme principles and ideas...
or future development.
I remember reading about Racket designers taking a decision to split the
software,
one to serve the minimalists,
one to serve the rest.
Is there a list-serve, Racket or Scheme, that has such a focus?

In case it helps with the response, I am interested in reading more about
minimalist endeavours.
Thanks
Don Green
