Integrating these web components into our React codebase has been pretty awful--more of a web components thing than a Lit thing, IMO. We have "scoped styles", except for certain important things like font sizes, so tons of little regressions everywhere when we swap in the web component in place of the old React one. DX-wise, we lost a lot, too. I assume the tooling will get better, or that we'll figure it out more, but it's mostly been a drag

Are you migrating from react to something else? I see the appeal of web components as a middle ground for base library when different frameworks coexist (temporarily or not), but everyone is so hellbent on monoculture this days that I don't see the point really.
