I am 100% with you. Love python the language, but the ecosystem around it was never thought out properly. It grew organically over the years and it is a complete and utter mess.
My last attempt at using pip this very morning to install a bunch of deps crashed and burn with an obscure python stack dump.
Oh, and, in your taxonomy of partial and inadequate solutions, you forgot to mention anaconda, possibly the most invasive package management solution I have ever seen, which exhibits the same problems pip does, i.e. where each install is a total crapshoot.
