Default Debian Trixie out of the box configuration without changing any systemd config file allows gnu screen to work as it always has. There would have been great uproar and screeching if basic 'screen' detach and resume functionality had broken anywhere between Debian v11, v12 and v13, and it has not.

I'm assuming this is same for tmux but hasn't tested it.

Is there some major distro out there that has the config flag set the opposite of this by default?
