I mean they have to be for now - you're just being semantic for the sake of it a bit. I will say as a team that utilizes Lit for our design system web components (which none of our users even need to know or care about no matter their framework btw). The Lit team are huge advocates of aligning with native standards (now or what they might be in the future) and working to establish or push them forward. The goal of the project for a lot of these issues truly seems to be to eventually not need them to be a part of Lit at all.
