The fix was only for not breaking the Emacs build.  If you then load
Org without rebuilding all Org files, you will still get the error,
and AFAIU that's by design: the Org developers _want_ you to get that
error.

Yes.  And not just from any "compile time", but specifically from
compile time during the Emacs build.

The intent was to get Org out of the way of Emacs developers who build
Emacs many times a day, but not necessarily start Org.  The rest is by
design, and if you don't like the results, please take that up with
the Org developers, who decided on this design.  We in Emacs just
import Org's code.
