Yes but that model conflicts with the human notion of being “logged in” to a system.
And the current behavior is literally what you describe. It’s just the quirk of subreapers being implemented recently that daemonizing a process wasn’t local to your session.
It makes zero sense that a process that double forks is reparented by init instead of your session leader. If how things worked currently was proposed today it would sound crazy.

It's a windows acolyte mindset. Many people don't imagine that a login is just another program, rather than the parent process.
