We kinda did with the Metroid manga.

But I'd definitely like to see in supplementary material how the Luminoth are doing since the end of the event of Metroid Prime 2: Echoes.

I'd said none as they deserve peace,the Luminoth on Aether particularly. Whenever she set foot back on a plane5 in a game bad thing are happening or happened, and planet tend to blow up on her second visit 2 out of 2 (Zebes and SR388).
