It is obvious to you as experienced human. For a computer (or even a 
novice user) this is not obvious. It would need a lot of coding to specify 
which tags are whole independend, which influence one another, ... Thus we 
have choosen the current variant which means a simple and understandable 
rule: Only use defaults when not already tagged.
