??is "generalized" (in a certain sense) toric algebraic geometry essentially just "affinely relativized" such?? ...??or something ??...

???something about ... ???plenty of morphisms of affine toric varieties (for example) that are like "inclusion of clised sub-variety ... ??...

???so what about certain kinds of geometric colimits of affine varieties, and/or of their associated ag theories, and so forth ... ???something about ones which seem "unproblematic" ?? ... or something ... ??something about "pair of polynomials with same nth order truncation", and so forth ... ???something about "pair of [vector space with linear operator]s, together with isomorphism between their kernels", and so forth ...

??is there something about ... ???certain kinds of geometric colimits involving "glueing together closed pieces" (or something...) tending to be _un_problematic, so that attention is more focused on some problematic aspects of "glueing together open pieces" ??? .... ???and so forth ?? ...
