Can you tell me to whom we would address this proposal? and who has the authority to accept or reject it?
It's a community decision whether to accept or reject a proposed
feature. We have some documentation on the subject here:
If it's a "sizeable" extension (adding a new, novel datatype or syntax
production), I'd recommend proposing it as an RFC to cfe-dev to gauge
community interest, get design questions answered, etc. Having a patch
already queued up can help with the RFC, but isn't required if you
want community input on decisions before submitting a patch. If it's a
"tiny" extension (like adding a new attribute or a new builtin), then
a full RFC may not be necessary and you can go right to discussing the
feature in the patch review.
