If you don't do it that way then resizing the terminal corrupts what's on screen.

Yes, I'm sure it's possible to do better with customized C, but vim took a lot longer to write. And again, fullscreen apps aren't the same as what Claude Code is doing, which is erasing and re-rendering much more than a single screenful of text.
It's possible to handle resizes without all this machinery, most simply by clearing the screen and redrawing everything when a resize occurs. Some TUI libraries will automatically do this for you.
Programs like top, emacs, tmux, etc are most definitely not implemented using this stack, yet they handle resizing just fine.
That doesn't work if you want to preserve scrollback behavior, I think. It only works if you treat the terminal as a grid of characters rather than a width-elastic column into which you pour information from the top.
Counterpoint: Vim has existed for decades and does not use a bloated React rendering pipeline, and doesn't corrupt everything when it gets resized, and is much more full featured from a UI standpoint than Claude Code which is a textbox, and hits 60fps without breaking a sweat unlike Claude Code which drops frames constantly when typing small amounts of text.
