Thanks, Michel.

I was actually asking from the point of view of IDNA200X itself, i.e.
not just ccTLDs (though I do appreciate your work).

Are we likely to introduce an actual contextual rule for ZWJ/ZWNJ? If
so, which scripts would be included?

Myanmar could be, but frankly with Unicode 5.1 adding a character to remove the need for it, it makes sense to encode the country name using the new character (I have a note about that in the document). My understanding of the Myanmar update is that it removes the need for Joiners in the Myanmar script through the addition of U+103A MYAMAR SIGN ASAT.
