There is no doubt that, when using Lit, you're going to re-write portions of some existing framework. That's the big selling point: You're going to write them your way, and only the ones you need. Instead of inheriting and learning React (or Angular, or Vue), you decide what syntax and behavior your components will have -- all the way down to "bare metal" of when and if they render and with what contents or results. None of this is specified by Lit so you will be re-writing those pre-fab aspects of any canned framework.
You'll also be writing any kind of routing or other validation tools that you need. Which is actually glorious! You get to make one that's small and easy to keep in your own head, yet flexible enough to be extended and expanded in any way that you can imagine.
There isn't a React component that would have helped me build this game[0], other than very basic stuff like buttons. But with Lit, I could write components all they way down to SVG graphical elements and create all kinds of new behaviors that React doesn't understand.
Sure! What I mean is that, since the web components are bare metal, they can be very specific to my game. I have SVG components that return graphics, change colors, move themselves around, etc. based on properties and state in the app. Because they aren't based on canned components, I don't have to worry about shoehorning what I want into a React component that's really made for something like text or a dropdown, etc.
