Unfortunately, Go provides no way to detect when a connection has been fully closed without trying to write at least one byte to it

Thank you! As a newcomer to Go, this problem drove me crazy. In Java, if I were running a select loop, I can just get an event that the remote end disconnected. I'm writing a HTTP (1.1) proxy for delivering webhooks in Go as a side project, and the way I "solve" this problem is by having an idle read timeout on the connection. Of course, this only works because it's HTTP, and the intended behavior of my proxy is to close the connection after a request-response interaction anyway.

I'm exploring possible solutions and plan to publish a blog post about it

Very much looking forward to it!
