Well, in the bit you snipped, I did say that we should do something 
different :-) The enumeration type proposal is one implementation of the 
first thing I said, namely making a set of mutually exclusive options.

We do need to be quite careful about renaming existing options without a 
very good reason, though. It might well be that the only way to achieve a 
consistent result is to do so (and perhaps provide backwards compatibility 
aliases), but we should tread carefully.
