There are plenty of resources about WebComponents. Nearly none of them are about WebComponents though. They are about Polymer. Or Stencil. Or lit-html. Or...
There's a Polymer summit. I don't think there's a Web Components conference.
It's probably the first time in the history of web standards that the new "use the platform" and the new "use the APIs" are rarely if ever mentioned in any of the resources dedicated to them.
People keep mentioning jQuery. However, as the platform develops, there's less and less need for jQuery (querySelector, fetch, etc.). The platform developed to include WebComponents, and they somehow don't reduce the need for libraries. Instead, they all but require libraries to be even remotely usable.
And that is specifically because of a new trend in web standards about which I have mixed feelings.
Specifically, more low level APIs intended to be consumed less by web client developers directly and more by web tool/framework developers.
The idea is that web standards will be able to move faster and satisfy real (vs imagined) needs better if there is more dialogue with "userland" solutions. I get the impression they don't want to spend a lot of time on API usability only to find there are major problems with or no value in the essential features. (For example, almost a decade was arguably wasted on XML as a way to extend HTML, while multiple frameworks found their own ways to do it and thereby also uncovered a dozen OTHER needs in the platform.)
So there's definitely SOME inaccuracy to the framing of using the platform being about not using libraries at all. But honestly I think this argument usually involves people talking past each other, not with each other.
