That should be fine.

My idea is to change `org-assert-version' in such a way that the check
is completely bypassed when `org-version-built-in-p' is non-nil (of when
some environment variable is set). As I said, `org-assert-version' is
not aiming for built-in Org compilation. Just for Org package
installation.
