Just curious, why not do it in 2 lines instead of 3?  E.g.

    from http import server as SimpleHTTPServer  # noqa: N812
    import socketserver as SocketServer  # noqa: N812

This way, we're more explicit in acknowledging the linter error, we save a line,
and it seems _slightly_ more readable to me. This method also seems consistent
with how some other popular projects handle similar situations (e.g.
https://github.com/pypa/pip/blob/master/src/pip/_internal/utils/hashes.py#L14).

I was trying to avoid disabling the linter. But all in all, my code is working
around the linter anyway, so we might as well be honest and mark it explicitly.
I'll go with your version.

+    from http import server as SimpleHTTPServer  # noqa: N812
+    import socketserver as SocketServer  # noqa: N812
