If both the motivation stage and the design stage both happen in the same repo I would like all PRs to be tagged as one or the other.
I’m worried that this change might actually compound the problem it is trying to solve. While it is disinviting half-baked and unwanted RFCs it is actually inviting new discussion of pre-RFC ideas into the official RFC process, in the same forum as the RFCs. A big part of the existing problem is that so many RFCs are simply not worth devoting precious time to because they are poorly-conceived, underbaked, etc. Presumably it will be easier to evaluate and turn away these small RFCs before they get too far, but they’ve still got to be evaluated by somebody with the authority to say yes or no. There may end up being more decisions to be made, not fewer.
