Italics aren't a novel concept.  The approach for encoding new 
characters is that  conventions for them exist and that people *are* 
exchanging them, people have exchanged them in the past, or that people 
demonstrably *need* to exchange them.

Excluding emoji, any suggestion or proposal whose premise is "It seems 
to me that  it would be useful if characters supporting <this or 
that>..." is doomed to be deemed out of scope for the standard.
