[Shapes] Should the default value of Shape.StrokeThickness be 1, and not 0?

[opcodewriter]

Description

The Shape.StrokeThickness property has default value of 1.0

        public static readonly BindableProperty StrokeThicknessProperty =
            BindableProperty.Create(nameof(StrokeThickness), typeof(double), typeof(Shape), 1.0);

This means all shapes have a stroke thickness and you have to set either a global style to remove it or set property to zero on every shape!

Wouldn't be better if it's the other way around? Not all shapes always need a stroke. Having StrokeThickness 0 as default would be consistent with BorderWidth (for controls which have it) which has 0 as default. Why should BorderWidth be zero and StrokeThickness 1?

In UWP and WinUI, the default StrokeThickness is 0.

In WPF, it's 1, but I think they realized it and hence it changed in UWP and WinUI
