My main concern with stopping to use only upper case ASCII letters is 
that is going to break many implementations. Is it really worth the risk 
of deviating from this unwritten rule? Data stability is important, 
please do not take the decision of moving away from the defacto standard 
of upper case ASCII letters lightly. lightly.
