My understanding of the resolution is the same as yours. As requiring the  
of special glyphs when they are all available leaves the door open for  
#12 use case, I think the only question left is Elika's "MI" use case.

In the example posted by John, I agree that MI is nicer in case (5) than  
but MM is not. So this could indeed be a reason to let the UA be smart.  
But should
that be by default, or opt in? Given that MI isn't the main use case, and  
for digits (which are), (4) is always better than (5), I must admit that I  
find the opt-in solution tempting. But at least now, I can see that there  
situations where all variant glyphs are available but using them isn't the
