Doing review and testing would be great. Marco was a very prolific reviewer.

I agree. The points don't negate eachother.
This also made me think about conteibuting with code reviewing. You see, for each action there's also a reaction 😁

Fewer contributors means less reviewing and testing, fewer eyes on the code to catch issues. 

Slowing down bug fixes and regular maintenance isn't necessarily a good thing.  

Development isn't just about new features, or even mainly about that.

I appreciate him. On the other hand, slowing down develkpment is not necessarely a bad thing.

More will come if the value is returned.
