I agree this discussion, outside of an interesting balancer shm change and proposed mod_dav enhancement change, should be largely status-quo. I will go so far as to veto the idea of backporting the helpers to 2.4. We cannot avoid admitting our errors in design of that released branch, and papering over them now accomplishes little. At best it would require an mmn check and only optionally consider their use at runtime, with no hard linkage, since such modules can't be loaded in earlier 2.4.x httpd releases. Decide our fixes for rev.next and make that available for authors to have a much easier time keeping binary compatibility with us, even in deep intrinsic structures as you hint at. One way to do this is to rev specific structure definitions... if the module wants to break over the way they customized their interaction with the structure or its indirection to members (e.g. const/non-const changes) then let them do that at the structure-relevant revision.
