Switching to Svelte could be a massive W for a small organization, they'll get inundated with a flood of highly motivated, skilled ex-React developers. Also if react is as probablamitc as people say (I'm veteran of the Angular/Angular.js transition wars so i don't know whats going on as much). If svelt et co. it helps a business not only achieve greater speed but maintenability long-run it's a competative advantage and should be exploited. much like how legacy c code is being handled due to its memory unsafeness. Would that happen?

Last tidbit Web Components are often suggested as a solution, they could lead to another layer of complexity. For instance, how do we manage complex, shared state across different web components that might be built with different tools like Lit or Stencil? How do components built by different systems pass information to each other without essentially creating an ad-hoc framework on top of the web components standard?
