As you surmised.

That distinction is effectively meaningless. There are any number of
entities that end users perceive as "characters", which are not
represented by a single code point in the Unicode Standard (or 10646) --
and this has been the case now for decades.

What you are missing is that *many* emoji are already represented by
sequences of characters. See emoji modifier sequences, emoji flag
sequences, emoji ZWJ sequences. *None* of those are specified in 10646,
have not been for years now, and never will be. And yet, there is no de
jure standardization crisis here, or any interoperability issue for
emoji arising from that situation.

There may well be interoperability concerns specifically for the QID
emoji mechanism, but that would be an issue pertaining to the
architecture of that mechanism specifically. It isn't anything to do
with the relationship between the Unicode Standard (and UTS #51) and
