tmux is a modern alternative to screen.

Oh, and while you are at it, have a look at mosh as well. Mosh bills itself as the ssh alternative for mobile, intermittent connections but it does take the idea of 'not all text needs to be written to the terminal, only the text when you actually look' even further.

Mosh also has lots of network latency hiding tricks up its sleeve.

I bet you could implement a fast-enough terminal in QUIC, and keep the idea of non-permanent connection.
