I see, I totally agree! I want to rewrite https://serverjs.io/ https://serverjs.io/ at some point, and I'm thinking about what functionality to add. e.g., CORS will probably be a config toggle instead of having to add custom middleware. But what about things where it is purely an option? There's a slippery slope there IMHO. Database connection? For a server library, no way. Key Value store? Also no way... no, wait, those are used for sessions, now you have to either do no sessions by default, have in-memory sessions which are super tricky (because they "work", until there's tricky production issues) or add Redis/similar connection. Same for rendering templates, I added the 3-4 most common but not others and feels really "meh". It's also A LOT of work to add the top 3-4 options, even without documentation.
