Sure. But without seeing the other sides argument, I have to wonder if their point wasn't that they're not designed to be stable for the purpose of identifying a service/thing on the Internet; things can and do move and change. Hardware failure is a good example of that. Just like a house address, those too are normally stable but people can & do move. Just with software, it's like we look our friend up in the white pages¹ prior to every visit, which one might not do in real life.
¹oh God I'm dating myself here.
I was on macOS when I typed it, there it's Control+Cmd+Space, and then search for "super" which gets close enough.
On my Linux machine, I can either do Compose, ^, 1, or Super+e and then search for it. (But both of these require configuration; either setting a key to be Compose (I sacrifice RAlt), or setting up whatever it is the IME I have is for Super+e.)
