I think benefits of using `StaticArraysCore` as a weak dependency are quite slim. Anyone who would like to use sorting on static arrays would probably load `StaticArrays` anyway? In which...

What's the issue with 3rd party generated functions? I would expect that correctly implemented generated functions should work fine.

Well, as far as I can tell that should not be a generated function but rather a normal one and rely on constant propagation and Julia's compile-time execution.

Anyway, I'm fairly indifferent regarding removal of StaticArraysCore as long as I'm not the one handling all the issues it would cause.

This is a nice direction of improvement. I don't quite get the difference between `ComponentVectorialType` and `PowerManifoldVectorialType` -- the second type essentially covers the first one as a special case?...

OK, then what about `VectorGradientFunction`? It would be fine I think.
