All in all, personally I would prefer if Solid placed less emphasis on creating ‘apps’. Everything is an app nowadays, and it indeed looks like you are building some kind of Appstore, which implies that Solid will occupy just another niche on the web besides all the other appstores that exist.
I’d rather see people say e.g. “I created a ToDo app using a React + Solid + Rust + Postgress stack” than that they say “I created a Solid app that manages ToDo’s”.
In the core of Solid initiative I’d rather see mostly a focus on standards specification, documentation, reference libraries and example code. The apps could all be listed in a curated awesome-solid repo on Github if you ask me.
