Ok, so there are no automated test for each release.

Thanks for the hint!

At least (some) stable release branches are being build now but it
seems that nobody is caring about the result. That's one of the things
I would like to address.

Ok, but that would be something that "all" -rt-stable maintainers
should agree on, no? At least to some degree to make the testing part
consistent.

Well, having the pipelines might be easy, but we don't have them yet, 
right? Reacting on the pipeline results would be the next step that
possibly could happen in cooperation with the CIP project.

But yes, generally speaking we want to help. But we don't have infinite
resources (as usual), so we'd like to know where most impact could be
achieved.

Are there any plans to build and test the stable -rt branches with the
help of automation, for example by using the kernelci infrastructure?
If no: Would that be something that the RT project is interested in?

I'm asking for kernelci because the CIP project is already using that.
They defined a clear set of supported architectures, kernel configs,
test suites and concrete hardware (to some degree). This allows them to
make sure each release candidate of each branch is in good shape before
doing the actual release.
