Even though I've never used Angular, and do not build web apps at all, we have put custom HTML elements to great use at work. It's also not about locking down styling, but it's a neat way to package up _functionality_ and behaviour that otherwise would be just defined ad-hoc in JavaScript, and to provide a dead simple way to (re)use that functionality in a declarative way from HTML.

Similar experience, it makes it easy to integrate components into partner pages because they can treat it just like any other HTML element and we don't have to worry about the vast majority of possible namespace conflicts thanks to the shadow DOM.

Right, and that is a separate tech from web components. React, for example, does not use web components yet does exactly what you are describing.

The problem web components is solving is just the strong encapsulation. Closing the escape hatches as it were.

HTML is supported natively in the browser, and custom HTML elements and their properties work at the same level as all other HTML elements as far as JavaScript, DOM, and dev tools are concerned.

React, while it may provide similar functionality to the programmer, is not natively understood, and while it can run in browsers, the 'components' in React are not handled in the same way in the browser as native HTML elements, JavaScript and its APIs don't know about them as HTML elements, DOM isn't aware of them (only their parts), and dev tools can't offer much insight because the app that's running is an unpredictable black-box to the browser.
