The maintenance thing means nothing to me, since I basically don't need any changes unless a new version of my Linux distro flavor of the day breaks it. There's been nothing new in Screen in the last 10+ years I've cared about.

And I don't use the screen splitting at all - I use splitting a lot in emacs, but never in the terminal, so that's basically a non-feature for me.

I want to create, remove and switch between windows, and have a status bar showing their names. That is all.

I guess these are the reasons I've never seen the point in switching.
