I've tried to ask on Remix's discussions, whether the use of SolidJS is possible within their framework, it seems to me from the first glance that porting it won't be a big trouble. It's really going to simplify full-stack development.
That being said the work has already started on a starter with Nested Routing/Automatic File Based Routing + Code Splitting/Parallelized Data Fetching/Streaming SSR/Multiple deployment adapters. We're given it the same focus on performance that we've given the rest of Solid.
Here is the recent Vercel Edge Function demo we made with it: https://twitter.com/RyanCarniato/status/1453283158149980161
