You can use `-webkit-tap-highlight-color` on your website or PWA and distribute it any way you want. It will just not work in non-webkit browsers like Firefox.

What apple does and what the article talks about: They have a CSS property that ONLY they can use, you can't put that in your PWA, it won't work (no matter the browser).

They just released this feature internally. We have no idea what their plans are for this. The web doesn't broadly and suddenly adopt features like this anyway. It's very likely Apple is working on something to allow 3rd party devs to start using it via safari.

This is much ado about nothing.
