I suppose the question is what the real problem for distros is: 

If it is the process of cherry picking and merging, then we could create a tag 
on a stable branch more frequently (e.g. every month), which makes it easier 
for distros to consume a number of security fixes, while not creating all the 
overhead of creating a release. 

Whether such a tagged stable branch is an RC (without a tarball) or not, would 
be a different question.

A fully tested maintenance release, created more frequently would be a lot more 
challenging and require a lot more effort.
I do agree with Jan that we ought to approach other distros and then re-think.
