Most people just don't know what they are talking about. I think the only way that web components would be winning is if they were designed around a single render function to replace react but of course then the entire react/svelte/etc community would be crying out because they can't compete with a natively implemented virtualdom so everyone would have to switch to web components. But isn't that the point though?! Making life exponentially easier for developing a web application?! We shouldn't have to need all these extra frameworks like react, the browser could simply give us a blazing fast virtualdom and then everyone uses that and gets on with their lives.
You only get two things with web components:
1. style isolation (imo everyone will switch to @scope because shadow dom is unwiedly to use, even me probably)
2. the tiny nice advantage of being able to querySelector("my-element") and being able to actually call instance methods on the thing that it gives back, directly. Dont really need that very often though, it just feels super nice.
The argument for web components is really meager and the tooling is far worse, like you said: SSR is missing, autocomplete IDE support for elements and their attributes is missing, bundling and minification is missing for the html templates and you have to do it all yourself. People are now showing off unminified js and ordering their imports manually like it's 2011 again and act like that's good. No of course that's not better than what we have. lit.dev is okay partially because I think the fact that they use web components is almost besides the point, it's just a single render function like you have with react again.
