One of our team (@mchandschuh) suggested this line could be substituted for a "IsAssignableFrom" check. https://github.com/pythonnet/pythonnet/blob/master/src/runtime/methodbinder.cs#L60

The plan would be to make the generic-locator code more effective.

I would recommend looking at the MethodBinder -- it appears to be matching directly on type and not using Type.IsAssignableFrom which should properly handle super types (going from SimpleMovingAverage to IndicatorBase)

We're not really sure the flow on impacts for the whole library -- is this feasible; or are other parts of the code dependent on this = statement?
