Flarum is already stable? Some extensions are bundled, but the remainder (500+) are by the community. The Flarum team has no plans to add more bundled extensions as this increases the weight on the core team, we are not a commercial product, we don't have paid developers, it would become unbearable.
Thanks for understanding 😉 Softaculous can consider installing the top most downloaded extensions bundled with their release, see https://extiverse.com/
