Yes, this is what I meant when I said the post is too snarky, but I don't think it's fair to take that as representative of all "webcomponents supporters". That JS exists to fill a gap left by the platform, and it's a gap that should be filled by the platform, but it's also a gap that isn't filled by the platform.

I disagree. HTML is a profoundly intuitive and accessible standard which reaches far outside the normal bounds of software developers. This is evidenced by the thriving diversity the web has experienced (before everything moved to closed platforms, that is). For static content it already provides an exceptional balance between expressiveness and accessibility, and the dream of web components was to bring that over to apps as well. And I really do think that idea is still a good one.
Sure, and in a single project at a single company that's probably fine. You've all agreed to standardize on a single version of Lit-Element and compile the whole project at once, so no worries.
But if the goal is to make Web Components standard units of UI across the web, such that you can grab a `color-picker` component and a `webcam-video` component and put them together into your `video-color-filter` component... well, if color-picker depends on vue and webcam-video depends on lit and you write video-color-filter in LWC, your project now depends on three web component libraries.
