The whole thing with the ending and K.E V.I.N. was a criticism of how formulaic/algorithmic things were with the MCU, especially with the 3rd act. The villain gets the same powers. The fights are a CGI mess. Corners get cut for budgetary reasons. Cameos and other characters are forcibly added to further the greater franchise at the cost of a more focused story.

Part of She-Hulk’s schtick is that she breaks the 4th wall, so it felt appropriate to me.
