Why do we have a BIP process? It seems like unnecessary centralization and introduces gatekeepers (BIP editors) and bottlenecks (BIP editors need to merge new BIPs and changes to BIPs). If something makes it into Bitcoin Core and/or other implementations and users run that code then surely whether it has a BIP or not is entirely irrelevant.
Similarly why should proposals be stored in a single repo? If I want to propose an idea for Bitcoin I’d rather just store that proposal in my own repo than submit it to the BIPs repo.
These questions were asked by prayank during a BIP process meeting in October 2021 and have been paraphrased.
