Here's an issue: react does not guarantee that the nodes it manages stay the exact same. So if something else causes a re-render, you may lose the attribute if it is also managed by react and thus overwritten by the reconciler.
And as I already stated, the DOM of the changed node will re-render anyways, only the virtual DOM will not precede that update.
If your goal is performance, better avoid unnecessary re-rendering of components. Fine-grained updates should be sufficiently performant already - and if they aren't, your problem is either somewhere else or react is not the solution. Maybe Svelte or SolidJS would be a solution in that case - that's all I'm saying - not that everyone should switch.
That being said, the best thing about react is the tooling, which makes for a developer experience unmatched by most other frameworks.
