Besides agreeing to all what you said, the other important part is:
even if we were to eventually go with Johannes grand plans (which I
disagree with in many apects), what is the harm in doing folios now?
Despite all the fuzz, the pending folio PR does nothing but add type
safety to compound pages. Which is something we badly need, no matter
what kind of other caching grand plans people have.
