I mostly agree with everything you say. However, it may
still be of interest to be able to bypass the dynamic
dispatch system and use converters with static dispatch. I
fail to see how wrapping arrays of user-defined types is
easier with dynamic dispatch though.

How do you import the converters from one module to another?
And how does type_info objects compare between dll
