Of course, we have to honor it. It's already defined as buffer-local.
It should be easy/trivial to support. At least window-area-factor was
trivial and I see no reason why window-min-height should be any
more difficult.

I'm not sure I'd want to include display-buffer in this system, tho
I guess it might make sense.

I'm not referring to the functionality it provides, but to the way it
does it, i.e. to its code. But it's really not that important: just let
the C code do its thing, hoping it won't mess up majorly (i.e. it won't
delete windows that don't absolutely need to be deleted), and then do
the actual size-choice in Elisp by trying to resolve the CSP.
> Doesn't it try to give all windows the same size?
Yes, except for the window-area-factor detail, but again, this
isn't relevant, really.
