This seems far outside pg_config's charter. It is a simple
information reporter that can be run by anybody. Making it able
to mess with (or even look at) postgresql.conf introduces a host
of permissions problems and logistical issues.
I don't really see what's wrong with using a text editor anyway ;-)
