Output to Alternate screen

[reegnz]

Well behaved TUI-s I've worked with tend to utilize the alternate screen if the terminal emulator supports it.
My gut reaction when using gemini was, it destroys my terminal history scrollback as it does not use the alternate screen.

I'm still coming to terms with whether gemini output should be part of the usual terminal scrollback, or just be on the alternate screen similar to when you open vim, or other TUI tools.
Gemini CLI seems to sit somewhere in the middle: it's a TUI, but also behaves a bit like a shell.

So what are people's thoughts on this?
Does Gemini CLI output belong to the main scrollback, or should it be written to the alternate screen and destroyed when the user quits gemini cli?
