What capabilities do you need that current web browsers don't satisfy? I hear this argument quite a bit with Safari bashing. While Apple does seem to favor the "native" approach, I also use Mobile Safari exclusively for my own apps, and it works fine.
I mean, it's still a valid point even if it's a fixation. The enshittification of the web to work "only on Chrome" while Chrome is controlled by an advertising company whose motivation is to sell ads with it over providing a good consumer-oriented product is a problem.
