I asked around way more, but the TL;DR summary is that it never worked and that no group is able or willing to do the verification for a full SRU.
Backports would therefore be the option to go, but due to the (probably trivial once you know the fix) complex build issue it not feasible for me to do at the moment.
I'm open to help by anyone and willing to assist, but right now I just can't spend the time - therefore community help for the backport is welcome.
