> fonts are larger than you might think because they need full Unicode support

Correct me if I'm misunderstanding, but don't the vast majority of fonts _not_ include full Unicode support, or even close to it? I know of GNU Unifont, but not many people are using that on the web...

I take your point on selectively downloading the relevant glyphs for the user's locale, but this could be done by the browser too - it is aware of the locale.

full coverage, yes, that's relatively uncommon but the most popular fonts will have a wide variety of languages and that adds up even if you don't support Chinese but do want coverage of the range of fonts designers want to use.
