Yes, because by definition legacy industry-standard encodings not in
widespread usage prior to 1993 do not qualify for the
backward-compatibility requirement.

The necessity had to do with interoperation with existing
implementations, not with the need to support particular languages /
writing systems. For the latter, it has never been a necessity to add
pre-composed characters.

I'm simply telling you what the policy of the Unicode Consortium is.
