On advertising nightlies: to me this is like giving up any hope on progress towards R1. But if that’s the way most people prefer, let’s go with it. No releases to support, it would be less work for the devs. But it is in contradiction with the “we need a stable platform to attract devs” idea.
As for attracting new devs: yes, it definitely is a good thing. There is way too much work for the current team, taking care of both the OS and many of the applications. And we are quite welcoming to new developers even if we are strict on following the coding guidelines (like any sane probect, I’d say)
