Is there a good reason these composite emojis aren't all single code points? They have to at least mostly be separate images to be rendered, so it's not like it's an impossible combinatorial explosion. I remember there are only on the order of 1000 valid combinations.

I would assume for backward compatibility. If you don’t have the font with the updated emojis you can still get the reference.
