I was hoping that i'd agree but check the code for Mnesia for example: https://github.com/erlang/otp/blob/maint/lib/mnesia/src/mnes...

Numerous functions missing essential code documentation all spread in a single file, with commented out code committed in git.

I really wish there was a way around

    #ifdef VXWORKS

It really makes parts of that codebase dreadfully hard to reason with imo, but at the same time, I appreciate you either do exactly what they did, or you don't support the platform.
