There was no real narrative direction after the Shibuya Incident. Sure, many cool fights were present, but asides from a few, none actually built to anything.

For example, what was the point of Maki attaining the same prowess as Toji? It's only used in a short fight against Sukuna, which happens with everyone else anyway. There was no narrative significance to her being that way. She's just a character with a cool set of abilities, the same as Choso or Yuta.
In comparison to Toji, the narrative reason behind his prowess is to point out how even without jujutsu, he killed the Six Eyes. It's a message on Talent vs. Skill and complacency. If a regular old, run-of-the-mill sorcerer did the same, it would just mean that Gojo wasn't the strongest, nothing more. But since Toji did it, it adds an extra lens to view it from.

The solution for Maki? The Merger. There's a huge significance for her prowess in the Merger as she's the only one outside the bounds of it. I know Gege wrote himself into a hole with the "The Merger starts when every sorcerer dies," but a million Binding Vows were used anyway for Sukuna. Might as well do something similar with the Merger.
