Of course, no one could be expected to keep track of all those things.
Such is the nature of writing software that runs in a Lisp image,
where anyone can use anything, and does.

I mostly agree with you.  My request is simply that, when a change has
the potential to break third-party packages, and it's a change, such
as this one, that mostly moves code around for organizational
purposes, that it be delayed until the next major version.  My goal
for such a policy would be to reduce the frequency of such changes
that third-party package authors have to write compatibility code for.
The (if (version< org-version ...)) workarounds become confusing for
authors and users, and somewhat of a maintenance burden.

That's a very clever way to do it!  Thanks for your work on this.  If
it's feasible, you might also consider allowing committers to put such
a header in the git commit log and parsing it out of that, which could
make it even easier.

Thanks,
Adam
