Checking out the initial request on github for this feature I wonder why is this necessary? What access to the local network does the browser provide, or need to provide, and why isn't this something developers are more concerned about? I had a feeling this was possible as I see lots of mdns requests when I connect to certain things running sockets.
Never knew that this existed. Thank you!
