Good point, though bugs can easily creep in with such simple edits: in your copy&paste monospaced digits example you lose the ability to have both monospaced and proportional digits via a stylistic flag (and those are useful: use monospaced in tables, use proportional digits in text) Also it's many files, not just one (though hopefully variadic fonts will catch on), so unfortunately patching fonts is a bit more complicated :( (but if it's literally close to just one thing, that it could still be worth it)
