Of course I know this is two different committees. I'm not talking about that level of separation but splitting Unicode in Unicode proper and the emoji in another standard. Emoji standardisation is orthogonal to encoding present and past writing systems once the set of existing Japanese emoji were encoded. So it became a shit show as soon as the standard created previously non-exiting characters as emoji. In comparison, if you create your own alphabet it won't be included, so newly created emoji should be treated in the same way: being excluded of the standard.
