You got me wondering here. Is it not possible to pass an array of size_t to
the size_t* parameter, instead of a single size_t, and then encode the
layout of X1 in it?

Yes, that is what the flat reflection does. But during this operation the
X1 type flattens/decays to the the basic types. You can not get X1 from a
record of {int, int}. And you can not remember X1 because it is not
registered in the map.
