I had reservations about fully embracing your "incoherent manifesto", but open adoption of New-School Kitbashing (by that or another title) would provide a proof-by-practice of most of your argument as I understood it. Adequately communicated there would be a lot of lessons learned and shared, probably in a more parsable / exemplar-driven-rather-than-theory-driven model than The Forge usually provided.
How does one Tulpa this into being? I think you're really on to something here.
