I think this proposal is totally fine … and we more or less do it like this already anyway.
I have a suggestion to move the RFC pages from the Wiki to the repository. Reasons described here: https://github.com/pgRouting/admin/issues/19
Sorry, if it was me maybe, who suggested using the Wiki at first. Is there a reason not to use a regular repository?
I followed Daniels suggestion
and created this PR https://github.com/pgRouting/admin/pull/22
Where you can write your feedback
Also you can make your feedback in form of a PR or using this mailing list
We apologize, as this is our first RFC that we write, we are looking for the best way to handle them
