It might be simplest to align towards Unicode and UTF-8, while retaining ASCII commands, avoiding a plethora of options:
So one has the commands \colon for function “:" as is now, and the new \ratio for operator “:".
Then Unicode ∶ RATIO U+2236 is mapped to the same as \ratio, which leaves :
COLON U+003A the only possibility to be the same as \colon.
Such an option might be called say colon=unicode, and be a part other similar options.
