> The "community" is external to the development team
It is nonsense in much the same way that a "stable ABI" is nonsense.
Integrating with the rest of the community certainly requires an inventment and if you cannot afford the time, then "Arrang[ing] for a developer with at least 100 upstream commits to be permanently assigned to the development team" sounds like a suitable alternative investment strategy.
I can just see a new standard line in resumes:
> Linux Kernel Contributions: XXX commits over YYY releases.
