Never said I have used tmux or screen. Last option is best.

Things that I use: dtach for session handling. dvtm for terminal window
managment (though iirc it has scrollback, ether way I don't use it). Also I
dtach individual applications and not dvtm, since it is way more flexible that
way. So separate program would could be good for people who need it. Otoh if we
took my approach we would get this hipothetical app, dtach, dvtm, and real
terminal, all being terminals... That isin't so cool. But as I said I most
likelly wouldn't use such app. And having it separate would enable me to use it
only when needed. I.E. some REPL/interactive applications as someone mentioned.
Also speaking about wrappers there are even other kinds of wrappers:
rlwrap/enhance for providing history and line editing to apps. And thees apps
are cool too.
