It's rumoured someone could patch it and run their own. Haven't tried for myself. Seems like a lot of work and JavaScript is pretty convenient as compared to full page reloads or frames.
The entire premise is absurd. What application spends more time on SSR than data fetch, or other? Exactly freaking zero that ive ever operated.
Fwiw, I'd like this site to have fallbacks for non-JS users, but it's a heck of a lot of work to make everything twice and nobody asked yet or contributed a patch for even basic functionality
