Probably, but I think it bears saying something about how to handle
code points without the Emoji property set. IMHO they should be
handled as undisplayable.
This steps into user interface design, more than interoperable emoji
labeling and transport.
As such, it's outside of this specification and outside of the IETF's
expertise.
The Unicode consortium adds new emoji and combinations several times a
year, so depending on how often people update their software it is
common for a sender's and a recipient's systems to disagree about what
are valid emoji. This is not a tarpit we need to step in.
The language is intended to cover this sort of version mismatch, without
saying anything about the UI aspects of how it's dealt with, beyond
recommending that the site do whatever it normally does with Unicode it
does not current understand.
