I feel like the only purpose of Drake's character is to be a stepping stone for Koby. I don't think any of the supernova, except for Law and Kid, will ever be that important.
It seems as if as the manga progresses, the more irrelevant some of these supernova are becoming. Every arc, luffy and the straw hats grow, but the supernova don't.
Now you have it to where Nami and Usopp are going to be taking out Page One and Ulti, tobi roppo with the same rank as Drake. Zoro 1 shot Killer and Sanji memed drake in the anime.
Could Oda make Drake strong after wano? Possibly, but I feel like it won't happen because I don't think there is anywhere to take his character. The most important marines were always the admirals, Garp, Smoker, Tashigi, and Koby. Given how little we have focused on those characters, I don't think Oda really cares about Drake.
