According to mypy_primer, this change has no effect on the checked open source code. 🤖🎉

Ah, apparently _socket.SO_BINDTODEVICE has come up before: #13464 (comment)

socket.SO_BINDTODEVICE seems like it was available on Python 3.13/Darwin between December 5th (see #13196) and February 4th inclusive... no idea why. It's not available for me locally either (and not documented as being available on Darwin, I don't think?), so I've removed it from the stub again.

I guess it's back again?
