Who would do that ?
You ?
And which 73 others ? Unicode is Huuuuge...
Seriously : Such a proposal couldn't stop to "just" the "customary"
single-letter greek variable names we are used to and think of first.
There is no a priori valid reason to accept them and refuse, for example,
hebrew or cyrillic characters (and names), katakana, sinograms or greek
polytonic multiletter names...
The real question(s) would be "Where do you stop ? (And why ?)"
Furthermore, the question remains of what happens to those characters in
\LaTeX math mode (not obvious to me), what happens to spacing, alignment
and possibly kerning, etc, etc...
