Yet another option is to include the parts with proofs from P1 as an appendix to P2. An appendix is meant to be for referees. As P1 is not yet published, this seems the most appropriate.

if your 2-dimensional closed sets have at least 3 elements then one doesn't need any group actions and infiniteness, it's just pure synthetic geometry to show that you sill get an affine or projective geometry.

comment Cardinality of non-integer points in the translation of the Minkowski sum of convex hull.
counting integer points in $mP+nQ$ is quite famous question, related to mixed volumes. Perhaps you can use it to get $|S|$...

you need infiniteness to avoid a sporadic example related to the Mathieu group $M_{22}$, I suppose. Well, I don't know how to deal with the case of 2-dimensional closed sets (a.k.a. lines) being of size 2, and locally being an infinite projective plane.

2.1.11 is also a result that is very old, at least in geometric terms (I don't know what an "infinite homogeneous" means though). Does it mean that the rank is infinite?

2.1.12 is a classical result in projective geometry, any good book should have it. e.g. see math.stackexchange.com/questions/549099/… for a list of books.

Check out "A=B" book, it explains how to identify a hypergeometric function given by series. math.upenn.edu/~wilf/AeqB.html
