There are cohesive component kits versioned as whole package, but I never liked that to be frank. I think this is good evolution, just messy because it's new. I'm sure better tooling will eventually emerge.
Then if you have over the years collected a bunch of incompatible changes that you would like to do, you create a new library with a new name, and do all the changes there.
Now you have the first library absolutely never breaking compatibility, and the second one for your "I absolutely must change the API interface here" changes.
There are some good ideas around versioning here as well (by Rich Hickey): https://www.youtube.com/watch?v=oyLBGkS5ICk

I don't understand this. Either a new solution is better and we try to use that, or the solution is worse and we should avoid it. If it's worse, why should we build better tooling when we can just use a good solution from the get-go?
From my perspective coming from my experience both as a component kit developer and an application developer using that kit, having one component per versioned package is good. That we live in a world where larger packages are prevalent and thus tooling forces a developer to duplicate configuration everywhere is an unfortunate coincidence that doesn't take away the benefits of separating the project into one versioned package per component.
Also consider that it might not even be because of the development tooling, but rather VCS or CI/CD related.
From the repo's README:
> We have 16 open source custom elements:
It's feasible that GitHub also have some components that are temporarily or permanently private. Having one repo per component may help to remove the need for that distinction among GitHub developers, who don't have to first check whether to import a component from a public or internal repo.
