The difference is that the font/font engine needs to anticipate
that the combination will be desired. Please see attached graphic.
Without positioning rules, where should COMBINING CANDRABINDU go?
Does it make a little hat for our guy? Should it be centered, or
cocked to one side? Should it overlay and "turn that frown
upside down" and give him a nose to boot?

I agree that existing conventions should be supported.
