For these reasons we’re considering moving to a similar model as vdsm, having a smaller set of people with merge rights to make sure the patches get in in the right order and they meet our sanity standards (OST, bug’s TM)

just the sheer amount of backports needed (every patch). Doesn’t sound worth the effort of posting and reviewing(even if just formally) everything twice.
If you expect _every_ patch to be backported
We are trying to minimize backports between master and stabilization branches by creating the stabilization branch as late as possible. This means that both branches use 4.4 database script numbering, which should decrease the need for backports.
If we would create standard ovirt-engine-4.4 branch, then we would need to introduce 4.5 db scripts numbering on master and this would create huge overload when backporting all patches from master to ovirt-engine-4.4
So current master is meant to be our 4.4.2 release and we have ovirt-engine-4.4.1.z stabilization branch. Later we will create ovirt-engine-4.4.2.z stabilization branch and master will become 4.4.3 release and so on.
, just do nothing - let current maintainers do their job, and revert the occasional bad ones when needed.
And how would you prevent breaking the relatively frequent updates? The CI OST is not working very well (for a long time now) and while we are improving and stabilizing the infrastrucure it’s not really there yet to consider automated gating.
Engine is unique in oVirt set of projects, it’s the largest one by far and use maintainership per team or area (FE, BE, database, API…) and so we have a pretty high number of people merging patches but far less people keeping up to date with the project’s planning.
Otherwise, I think branching is a good approach.
