What features do you gain by architecting tmux/screen that way? It seems like you'd lose a nice feature, the ability to persist sessions' appearance after the client exits

The ability to render things client side in a way the server doesn't anticipate, e.g. native widgets on various platforms.
I don't see myself loosing anything of value? If the data you are talking about is e.g scroll back, nothing is preventing me from storing a wee bit extra metadata on the server.
screen/tmux is also all wrong: the "rendering" should be entirely client side, with server-side running the commands with pipes and keeping some state and history from which to render scrollback, but that's it.
