I have a strong personal preference against adaptive icons. I hate how they make everything look the same and less distinctive. I know apps are required to have them, but most apps still also package a "legacy" icon that has a distinct shape. It seems like every launcher uses the adaptive icons if available though and the extent of their customization in regards to icons is choosing which shape you want every single app to be.
I also know some icon packs change the shapes of some apps, but I want the apps' styles, not the icon packs', and I want all icons with legacy icons to use them.
Is there any current way to have this option to not use adaptive icons? I'm on a Pixel, so fairly close to stock Android.
