John's remaining complaint about the virtual function was the "need to recompile all when a cabbility is added". This would not change that. And I do not like this collection of random boolean flags more than the virtual function approach. The latter is at least consistent with the rest (we have virtual functions already) and more flexible (the trait could be something other than a 'bool').
