Yes. The upgrade to A is a breaking change that affects other libraries. So 
even though the new version of A works well and is itself stable, it should 
not be merged to STABLE until all other libraries that depend on it are 
stable. Then all of the libraries involved should be merged into STABLE at 
the same time.

I've updated the doc to make that clearer.
