(By the way, since Guido's retirement as BDFL, any major proposal doesn't have to just convince him, but a committee of people (as yet unselected).
I don't read the governance PEPs that way, FWIW. A major proposal needs to convince "Python Dev", as summarized, interpreted, and guided by either such a committee or by that committee's BDFL-Delegate. This has been the custom for quite a while; I don't think Guido has been a micro-manager in this millennium ;-), although the BDFL-Delegate custom is "only" about a decade old.
