I asked about this on the Discord, but didn't receive a reply after several days. Sorry if this isn't the right place.

Description

When the --uds option is used Uvicorn creates a socket with 766 permissions, accessible to any user on the server, and this does not appear to be configurable. What is the recommended way to restrict a socket to 760 or similar?

I could separately chmod the socket after it is created, but this leads to tricky questions about error detection and handling if the chmod doesn't happen for some reason.
