We are in agreement across the board. Though, non-exported types are
not actually useful outside of the module itself I don't believe,
assuming of course, that all types used in specs for publicly exported
functions are also exported. So your module_info(exported_types) is
really a synonym for module_info(types). I hope that description is as
clear in what I have written as it is in my head.

I agree, though I don't see why they shouldn't be part of the same eep?
