Also I found it weird that you mention Evan You WRT vite as a counter to why Rich might be up against stronger devs, but Rich made rollup, which was foundational to Vite's bundling.
Rollup is cool, but it's a very different beast from a f/e framework. For a lot of projects, migrating from rollup to webpack might be a few hours or a week. Migrating from svelte to react, is months if not many man-years.
My point is that you've seemingly taken points away from Rich for the same reasons you're giving Evan You validity.
Migrating between react and vue would take probably the same amount of time -- I'm not really sure what your point is here. My point is that you've unfairly discounted Svelte on the same standards you're raising vue.
I’m not sure what your argument is here, but I’m pretty sure you have it backwards.
The fact that it might take a while to migrate a svelte project to react is not because of poor documentation or tooling or communication or anything like that. It’s because so many things work out of the box in svelte, and to do the same things in react would take tons of boilerplate or third party libraries. Some things may not even be possible to port, at least not easily.
This doesn’t show that svelte is bad though. It shows that react lacks functionality and is more difficult to use.
