>Corporate will not configure anything unless it costs them millions.

Of course they will if it has a purpose. Not everything is driven by money as you suggest. Besides: corporates have internal resolvers anyway.

>Same for Mobile (which breaks frequently but thank you very much)

No. If it does, complain to your ISP. There is no reason why an outgoing port should be blocked.

>and same for wireless networks.

They will update too.

>Nobody will update their machines that haven't been updated since the 90s because your protocol needs a new port to be freely accessible. Nobody will thusly adopt it and in turns nobody will update their machines.

Dangerous assumption. Opening a port does not need an update. It's TCP, the same protocol as http on port 80 or 443.

This is a minority problem. Networks do work.
