Dynamic island is going to take a few updates to work out most of the kinks, or even until next gen phone even. Being limited to Pro phones makes the userbase relatively small atm, I see lots of issues of it blocking things not only on Apple's side, but app developers as well - like a search bar on top of the app or display info being covered by the island.

Not being on a regular model probably slows the development and evolution of it, bit of a catch 22.
