Your argument seems to boil down to "no-one uses the prompt", so why not just get rid of it?

[Hardly.]

[I]f this is not an accurate summary of what you're trying to argue, then I honestly have no idea what you are trying to argue.

I'm surprised at "no idea". He's been clear throughout that because there are many alternative interactive interfaces besides the CPython interpreter itself, to be truly effective the warnings need to be propagated to those, and it's not automatic because most of them don't use the interactive interpreter. IIUC, at least in IDLE it's already possible to get them with some fiddling. Since it's debatable how important this is to interactive prompt users (especially those on POSIX systems), he thinks that to be effective it requires much more to change than just the CPython interpreter, and since it may annoy more users than would be helped, he doesn't seem to think the change is justified.

I think personally I tend toward the side that the proposed warning display is a good idea even if of limited benefit, it's not likely to bother too many users, and it can be extended as desired to the alternative interactive UIs. But that doesn't mean I don't understand his point of view.
