That's one of the huge benefits of web components -- third parties can iterate quickly to find useful patterns, then browsers can just standardize the best/most popular ones. The old way of discussing ad nauseam in committee then implementing straight in the browser gave much less useful elements. (And it's much less straightforward to convert a popular React component into something browsers could implement natively.)

I'm looking at hundreds of date pickers, carousels, autocompletes, customizable selects, data tables, modals (e.g. for media previews). They've been around for as long as there have been browsers (so, thrity years or so).
Can you point at any standardisation effort around any of these commonly repeated patterns?
input type="date" and input type="color" are only now barely making it into the browser.
