socket documentation should mention AF_UNSPEC in the section on constants and getaddrinfo() docs

Documentation

In the socket module documentation

There should be a mention of AF_UNSPEC alongside AF_INET, AF_INET6 and AF_UNIX in the constants section.
Also e.g. in the getaddrinfo() entry, it should be mentioned you can pass socket.AF_UNSPEC instead of 0.
The difference matters if automated testing is checking type annotations (at least I had this issue submitting
a pull request for pythonosc).

The default family argument for getaddrinfo is 0.
This has type int, not type socket.AddressFamily, whereas socket.AF_UNSPEC,
has the type socket.AddressFamily, but corresponds to the integer 0.

This makes a difference when type annotations are being checked
and the argument to family is expected to be of type socket.AddressFamily.

Comienza en la documentación del módulo socket, concretamente en la sección de constantes y en la entrada de getaddrinfo(). Menciona AF_UNSPEC junto con AF_INET, AF_INET6 y AF_UNIX, y documenta que se puede pasar en lugar de 0 para el argumento family. Se considera terminado cuando ambas referencias solicitadas explican la diferencia relevante para el tipo.
