Well, the discussion is not about whether removing centos/rhel alone, 
which really is redundant -- it's mainly about the version piece, which

Totally agree if we really speak about application. But is ruby base 
image an application? It is rather a tool to create applications on top 
of it, where the rest of the system matters.
