An input into the evolving emoji specifications might be useful, so that 
the issue of why they are so unsuitable for identifier gets some raised 

The twin problem with emoji is first, that they look very concrete when 
presented as images - unlike some "foreign" scripts, everybody thinks 
they can read/recognize them; and second, that they are incredibly 
appealing to people who view DNS labels as expression of their identity.

 From a technical point it might be enough to point to the IDNA 
parameters, but from an outreach point of view, this falls woefully 
short. (I do like Andrew's various summaries of the issue; they should 
get incorporated into UTR#51 ...)
