A lot of the emoji were encoded because they were in use on Japanese mobile
phones. A fair proportion of those may very well not meet the selection
factors (see <https://unicode.org/emoji/selection.html>) required for new
emoji, but they were definitely within the scope of the Unicode project as
encoding them provides interoperability.
As for newer emoji, whether they are encoded or not is up to the UTC, and as I
say, they apply (or are supposed to apply) the criteria on the “Submitting
Emoji Proposals” page. There is certainly an argument that the encoding of new
emoji should be discouraged in favour of functionality at higher layers (e.g.
<img> tags in HTML), but, honestly, I think that ship has probably sailed.
Similarly there are, I think, good reasons to object to the skin tone and
gender modifiers, but we’ve already opened that can of worms and so will now
have to put up with demands for red hair (or quite probably, freckles,
monobrows, different hats, hair, beard and moustache styles and so on).
