I'm of the opinion that macOS needs more of this kind of OS unification across the board. There is no reason to have different icons for the same apps and the bloody circles and tilted icons are dreadful.
Most hardcore Mac users hate this idea of unification but I really want it to go so much further.
The only parts I want apple to leave alone are things like customisations that iOS lacks completely. I should be able to arrange and change everything in macOS to look exactly like iOS "If I want it to" or like anything else. Since apple introduced system integrity protection and blocked downloadable apps by default, I worry MacOS will continue to get locked down to a point where it's unusable for me. That you can still edit the .app files/folders is amazing and long may it continue.
