Should `socketserver.BaseServer` have abstract methods?

Feature or enhancement

Proposal:

socketserver.BaseServer is documented to have the methods fileno, get_request, and server_bind, but it doesn't actually have these. They're implemented on the subclass TCPServer instead, and TCPServer is the only direct subclass of BaseServer in the standard library. Of the three methods, get_request is the only one called within any existing methods of BaseServer.

This seems like a situation where BaseServer is acting as an ABC with these methods expected to be implemented by any subclass. Abstract methods weren't available yet when socketserver was added. Does it make sense to use them now? I couldn't find anyone suggesting this on the issue tracker or on discuss.python.org, so I don't know if this has been considered and rejected before, or never really considered.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

从 socketserver.BaseServer 和 TCPServer 入口点开始，重点关注 fileno、get_request 和 server_bind，以及 BaseServer 当前如何使用它们。查看链接的 PR gh-127976，并确定将这些方法设为抽象方法是否保留文档化的子类契约；达到有相应实现和验证的文档化决定即表示完成。
