Hey piva00, my name is Tracy and I'm James' colleague at CloudBees. I think the project my team is working on may help you with the pain you're describing here.
We've made a curated distribution of key integrations and plugins for Jenkins and this distribution protected our users from the breaking upgrades related to SCM API 2.0, which includes the Git plugin upgrade you mentioned here.
If you're interested, send me an email ([email protected]) and I'd be happy to talk to you more about the problems you're experiencing with the plugin ecosystem.
