OK, I'll simply PNBLACKLIST all the recipes your AUH upgrades break or stop doing the CI builds completely.
Having latest versions is nice, but this approach to regressions introduced by version upgrades is quite a pain already.
I do test all my upgrades on the AB. For major ones like python or openssl, I run meta-oe builds too.
If the AB gives a green pass (which it did), then the upgrade works as intended. If you think AB is not doing enough testing, find the gaps in the AB matrix and address them.
