Red Hat obviously wants to change people's vocabulary but "Dockerfile" is basically an industry-standard generic term by this point.

That is true, the same for "to google" if people mean "to search". It does bury the generality of the concept though. Like I said, a nitpick.

I think it's also worth noting that the Dockerfile format is still driven by Docker, and there have been zero extensions to the format by Podman folks, so Containerfile==Dockerfile.
