I think it would be totally reasonable for a core member to say something like, "I'm uncomfortable with a keynote about this compile time reflection from Person1. I think it could look like we're endorsing it more than we are prepared for." That's exactly how I might think and talk about some extensive complex proposal from some outsider for a problem that I have some ideas on how we might want to solve. All the people upset about the keynote changes describe it in such like exaggerated form, that to me it's hard to just believe that they are the reasonable ones here.
