The only reason why I don't see it is due to the tease of the SSG. That to me sounds like another group of individuals who will pose a threat to the crew in the future or final war. I personally don't expect to see Vegapunk until next arc or the following tbh. He's always felt like a post-Smile/Wano issue to me.
Introducing a mega big character this late into the story sounds like it will totally take away from what is currently going on and I personally don't see it
Edit: in fact, I believe that precisely due to Vegapunk explaining devil fruits is the storyline where Luffy learns awakening. Maybe not exactly from Vegapunk, but potentially from some new ally scientist to who teaches him.
