Let's put this into perspective. Unicode 13 added 5930 characters. The
overwhelming majority of those (4939 characters) were CJK. Only 65 emoji were
added. You can view them here:

   https://unicode.org/emoji/charts-13.0/emoji-released.html

Obviously experiences vary, but none of these are things I've missed having
available to express a reaction.

Given that Unicode 13 was released in March, 2020, that's actually quite
impressive.

I think this assigns the base-emoji set a too much importance in the overall
scheme of things. But if the consensus is otherwise, I can live with it.
