Windows AF_UNIX SOCK_DGRAM request

[bridgewaterrobbie]

Is your feature request related to a problem? Please describe.
Per the blog post announcing AF_UNIX on windows, "Support for the datagram (SOCK_DGRAM) can be considered in future depending on the adoption, feedback and scenarios"

Not sure if it has been asked for elsewhere, but I have a use case where I would find this very helpful

Describe the solution you'd like
The ability to create SOCK_DGRAM AF_UNIX style sockets, thus allowing message boundaries to be preserved

Describe alternatives you've considered
Adding my own basic message boundary headers in a stream socket connection. However, I'd like to be able to plug this into existing libraries that expect datagram sockets without needing to be aware of such a header

Additional context
Note: I am not sure if this is the perfect place to put the request, but https://devblogs.microsoft.com/commandline/af_unix-comes-to-windows/ links to this issue tracker

Thanks!

Good as any (there was some precedent set).

This would be very helpful indeed 👍

For what is worth, missing SOCK_DGRAM support is also the reason why the Python maintainers chose not to expose the unix socket API on Windows [1][2]

I'm interested in this support as well; I have a library requiring UNIX datagram sockets that currently only works on UNIX, and I'd like to make it work on Windows as well.

My usecase is this:
UDP-like socket with built-in ACL. No need to perform authentication as it is authenticated and is managed by the OS itself, locally. Probably more secure than UDP, too, and less overheads as we don't need to traverse the networking layer as well.

I am also interested in this because it is considered a blocker for exposing the AF_UNIX functionality in Python. Being able to use unix-style sockets would allow me to get rid of a lot of OS-specific python code.

Also interested in this. Want to build native windows application instead of running it on top of cygwin/msys2.
