For what it's worth, the Unicode Consortium seems to be trying to reign in the emoji explosion in the last few years. For example they won't process any new proposals for flags [1][2]:
> The Unicode Consortium will no longer accept proposals for flags. Flags that correspond to officially assigned ISO 3166-1 alpha-2 region codes are automatically added, with no proposals necessary.
And they decided against adding Multi-skintoned Families to the RGI, as in, vendors can encode them if they really want to, but it's not recommended. Apple for example replaced their more complex family emoji with the recommended silhouettes afterwards [4].
