Humans are very good at distinguishing shapes and colors. Visually distinct icons of various shapes help build muscle memory and quickly find the needed option.
One of the worst trends in icons is this insatiable desire to put different icons into uniform shapes.
For example, this trend resulted in tragic replacement of beautiful varied and distinct Android icons that were introduced in Android 5 to the uglicity we have now.
On iOS, beautiful SFSymbol icons that floated beautifully on flat surfaces since iOS 7.0 were encased in absolutely similar circular 'liquid Glass' blobs. Sad.
