If 'base' follows the package version policy, then it does not make sense. 
Does 'base' follow this policy?

I admit I also used 'base < 5' a lot, since in my experience, there was no 
breakage of my packages within 'base == 4.*'. If module XYZ in base 
changes, then according to the PVP, the major version of 'base' must be 
increased. If I do not use XYZ this does not matter for me. The problem 
for me is, that 'base' is still large and thus there are many modules of 
it, that I do not use.
