All the built-in packages will be affected.

Let's first try to report and see what the reply is.

Sure. But, as I said, let's first ask Emacs devs what will be the best
formulation for alternative instructions. I do not want to invent

Let's not think about this too much just yet. We are still discussing
ways to improve `org-assert-version'. Maybe extra instructions here are
not necessary.
