The default strokeWidth should be 2

[SantosVilanculos]

A stroke width of 2 is the modern standard because it balances legibility with visual weight. While a 1.5 stroke can appear thin or blurry by failing to align with the pixel grid, a 2 stroke stays crisp and high-contrast, especially at small sizes (like 24px) or on dark backgrounds. This "round value" ensures the icon aligns reliably with the grid, preventing the "fuzziness" caused by anti-aliasing on thinner lines.
