Yes, we also don't use ":latest" in any of the other tests, so pinning to a 
specific version also sounds like the better idea to me.

Anyway, if we really want to drop Python 3.8 (which we likely should do now 
indeed), we also have to update "configure" and 
docs/about/build-platforms.rst and likely some other spots... John?
