That there may be useful things provided by multipath per say is out of question, it's more how useful it is to package yet another kernel into the repository. It's very much an edge case variant at this point (as you pointed out yourself).

If you're a researcher or thinker you will somehow manage to compile a kernel from the AUR and the resources to do so are not really that high.

Which is quite ancient actually. Also the mentioned support includes handling of vulnerabilities by our security team. Each kernel, especially when not in sync with neither LTS nor the default, creates overhead when handling and researching patches and vulnerabilities as they are part of the official repositories.
This can get pretty cumbersome and personally I don't quite see the justification fur the additional burden it creates.
My humble opinion is that multipath sounds nice but belongs into the AUR rather then into our repository.
