The set of users that is capable of doing this is vanishingly small. I certainly don't - while I use linux which uses the interface name, I never remember that my wlan interface is called wlp0s20f3. My ethernet interface name is even worse, it's enxx<mac address>. I also don't necessarily know whether the device is on wifi or ethernet.

There is no such thing in some operating systems, and again, this is not the behaviour required by the use cases in the document that passed WGLC more than a year ago and which is not on this week's agenda either.

Can we just stop digging this hole any deeper? Please look at the current drafts that are on the 6man and httpbis agendas.

just like what it would do with any other connection. This will address the common "I need to configure my home router" use case. It wouldn't address the "I need to configure a home router on this other interface that isn't the default interface", but I think that is super rare.
