Comment (by pento):

 The idea is to provide a consistent experience, so, emoji tries one of
 three options:

 - Use native emoji, so that people see the emoji characters they're used
 to, and use less bandwidth.
 - Use native emoji except for flags, because some native implementations
 support everything except for the full flag set.
 - Use images for all emoji.

 I don't think the font test would work - because emoji glyphs can be made
 up of several emoji joined together. For example, "🤷" is an emoji made up
 of a single character. "🤷🏻‍♂️", however, is made up of three emoji
 characters joined together - "🤷", "🏻", and "♂️". Platforms that don't
 support "🤷🏻‍♂️" will render it as "🤷 🏻 ♂️". There are many instances
 like this, where system fonts will still render the emoji, they'll just do
 it incorrectly.
