I think you may be conflating components and good old fashioned libraries. You can certainly make a component into a library but that's not their main use case.

I think you may be conflating components and good old fashioned libraries. You can certainly make a component into a library but that's not their main use case. Their main use-case is for organization and reusability within a singular codebase. I write reusable components all the time inside my codebases. I never have to target anything except the stack I'm using for my project.
