There is a straight forward rule for Greek, as you state. But applying
this as a default could cause problems when Greek letters are used
in mathematics. Sigma is used in statistics to represent standard
deviation. I'm surprised Unicode doesn't have a separate code point
for this considering its obsession with U+2126 micro sign, U+00B5 ohm sign,
U+2135 alef symbol (Hebrew, not Greek) etc. Perhaps it's because the others
are designators / constants rather than variables.
