I'm not 100% sure what a transient prompt is, but it looks like Starship now might have support for them.

Starship only supports this in PowerShell for whatever reason.
Edit: Doh. I see what you linked to now. Yea, maybe it does work in more than just PowerShell now?
Transient prompt basically removes your prompt decorations and replaces it with just `>` in your scroll back history in your shell sessions. In my case it's a slightly more complex transient prompt (datetime and exit code of the command), but still greatly simplified.
Makes cut-and-paste of history in to docs and stuff super nice.
