There is one. -X faulthandler. I'm sure others would agree about
-O, but that long predates -X.
So, the idea is that -X *can* be used by other implementations for their
own purposes, but there is certainly no requirement that they do so.
Our promise is that anything CPython uses it for is something we don't
expect other implementations to support.
