Since neither of these things are required by the packaging guidelines, I believe the premise of your argument is deeply flawed.
1) As i've said before, there is no packaging guideline requirement that maintainers restrict helper applications to libexec. Helper apps can go in either %{_libdir} or %{_libexecdir} (and really, helper apps should be able to go in %{_prefix}/lib under a simple multilib exemption rather easily now as well.)
2) the systemd exceptions allows placing files in %{_prefix}/lib rather than %{_libdir} (the exceptions allow both putting the helper apps in there which would generally be okay with just a multilib exception and the unit files which are arch specific data and therefore usually go in %{_libdir} and therefore needed a special exception). The only reason people can drag %{_libexecdir} in to this discussion is that helper binaries are allowed in either %{_libdir} or %{_libexecdir}. In the context of forcing people to use a specific directory not specified by standards its meaningless because %{_libdir} is a suitable alternative.
3) lennert is not asking that we give permission for packages to use something other than %{_libexecdir} if upstream doesn't support it. He's asking us to forbid use of libexecdir within fedora packages no matter what the package maintainer and upstream support.
