It can absolutely be done, and I'm doing that myself, but I often find
myself fighting implicit assumptions in the framework, and either I'm doing
it entirely wrong or these assumptions apply to the majority of users.
The most annoying instance is that there is a notion of a single "current"
state for every project and dependency. I can set up a copy of my pipeline
to implement a "stable" or "production" variant, but I have yet to see a CI
system that is powerful enough to analyze a stable branch for regressions
compared to the branch-off point without a lot of hand-holding. For each
release branch, I find myself copying the existing pipelines and pointing
the new instances at the new branch.
