We are tracking this in #3209, but it will likely still be a little while yet before we are able to release fully lit@3.0 versions of the library. Depending on install order and package manager configurations, there should be no issue in using our components in a lit@3.0 application. You will need to have both versions in your build, but in terms of client side libraries is quite a small price to pay. I can say that you won't be able to force the next version (via resolutions or overrides) without issue today, but maybe there's an interim step that we could do to unlock that in the time being.

As update being already worked upon, it is not an issue to include both versions now. And also no particular other urgent reason to override. swc seems re-exporting lit functionalities. I would be importing them, as we are anyway using SpectrumElement as baseclass.

It shouldn't be an issue to include both versions.

In face, if you're always importing through SWC then you'll always get v2, which means you wouldn't really be using two versions!
