Description
[Originally under #30079]
Primary branch: pybind/pybind11#4928
Closing because it is very uncertain when and if work on this will be prioritized. — IMO: Ideally the handling of multiple inheritance in pybind11 is revamped, by porting the Boost.Python approach: https://github.com/boostorg/python/blob/99a5352b5cf790c559a7b976c1ba99520431d9d1/src/object/inheritance.cpp
