Why does material design recommend a 2dp border radius for buttons?

I know people prefer rounded corners to regular corners (references: 1, 2, 3), but why is 2dp considered a proper value for border radius?

It a button that follows this rule more user-friendly than one with a 10dp border-radius or it is just a suggestion and 2dp is a minimum value?
