HMR is quite possibly the most difficult problem Ive come across for the fine-grained approach(yes harder than Suspense and Concurrent Rendering). Its harder than hydration since no expectation of things matching. So I consider the solution incomplete. Solid only preserves state above the change. Even Svelte's HMR which does preserve the state blows out nested elements when I last checked. This is a place where VDOM diffing has an easier time.

Should have asked you about HMR :)
