This is a limitation of UNIX terminals, in other platforms not tied to a no longer existing tty interface, this isn't an issue.

Unfortunely, given that we are stuck with UNIX derived OSes, this is indeed a possible issue.

However I would argue, for fancy stuff there is the GUI right there.

I don't know any GUI that beats tmux work portability.

Of course everything depends on exact nature of the work, but personally I would gladly leave text based interfaces behind, it's just that there's nothing better.
