luceos Indeed it does, but it makes you guess about the underlying reasoning. Some examples,
Use TypeScript (and all its magic powers) in frontend code
So why is this in the roadmap? Does it mean that when SuperNextGenScript is released, Flarum will adopt it? The roadmap reader cannot tell.
Performance optimizations
What is the goal here? Does Flarum need to be the fastest forum (how fast is that?). Or just "fast enough", whatever it may be? How does performance relate to the "growth of the software" as Jordan writes above? How does it compare to "beautiful software" as stated by Toby?
An official extension marketplace
Why? Does Flarum the OSS-org want to be financially independent by selling exts? Or does it want to optimize the user experience by curating extensions? Different goals produce different design decisions.
In the end, many people have different end states in mind and it will be hard to satisfy all of them. E.g. "the fastest" is probably incompatible with "should run in all environments" and "most features" is incompatible with "the simplest".
For the record, I don't want to sound negative or arrogant ? Just think that Flarum would benefit from clear goals.
