While all true, the above fundamental properties do not apply to e-mail 
addresses - which is what "mailbox" name in the subject line refers to.

Apart from that point, many of your arguments could be applied to e-mail 

What is missing is writing an actual statement that extracts from the 
useful statements posted here bye various people a single statement that 
squarely addresses the issue in the framework of email addresses and 
that could be the formal position of UASG on why or to what degree emoji 
fall outside the universal acceptance scope.

BTW, the argument made by some people here that they represent an 
"inferior form" (my term) of communication compared to natural languages 
is rather weak and I prefer not to rely on it.
