Yeah I suppose it's a tradeoff. I have had an excellent experience when not hydrating components at all, and I like their approach significantly more than other SSGs overall. My worry is just the massive scope of supporting integrations with all those frameworks AND its own .astro language / syntax AND server side rendering in addition to static generation.

To be fair, vite does a lot of the heavy lifting when it comes to supporting extra frameworks. If you look at the code required for astro to integrate with a new technology you'll see it's relatively straightforward.

For example, here's all the code in the svelte integration: https://github.com/withastro/astro/tree/main/packages/integr...

Wow. Good callout.
