The Godot maintainers have decided they don't support that perspective. In their words, they value "being cautious about feature creep" and "dedicated to high code quality"; they don't accept that all working code should be merged.

Aspiring contributors who'd like to make a different tradeoff are of course free to make a fork. But then all of the stuff in their fork won't benefit from the participation of the community, which I suspect most such people do value even if they identify as a "code first" person.
