I will point out a usecase where gpsr is not supposed to work, just so that its not something you try to work with.
$$ H = \alpha X + Z $$

Gpsr will not give the derivative wrt to \alpha for hamevo(H), because it does not scale the full generator of the unitary it is a part of.

Yes @rajaiitp this was my point that GPSR assumes something like $G.x$ while in the code we allow generators with an arbitrary dependence $G(x)$ to be written.
