Comment (by sergiomdgomes):

 Also, to address the browser compatibility question definitively, I
 understand and agree that Emoji support and JS support are completely
 unrelated, and ideally should be determined entirely separately.

 But for practical reasons, I think it's absolutely fine to just give up
 and unquestionably serve the polyfill to older browsers if that makes our
 implementation simpler or otherwise better.

 **Nothing will break** (it's not even a matter of graceful degradation),
 and these old browsers are [https://make.wordpress.org/core/handbook/best-
 practices/browser-support/ not supported by Core anyway], so let's not
 lose sight of the forest for the trees in trying to achieve rigorous
 correctness.
