What about in all-stop mode, where the CLI behavior is to change to a
new event thread?

I don't understand the need for this.  If you're going to let the user
type a CLI command, then before you can do that you have to make sure
GDB and the UI are synchronized on the current thread/frame.
Otherwise "backtrace" or "thread" won't work.
