So why does Proton work on multiple products at the same time? Simply because:
throwing more bodies at existing efforts has a point of diminishing returns and then a point when it even becomes counterproductive
given the lengthy minimum time it takes to perfect services, starting earlier lets us deliver more to the community over the long term
That’s why we bring new services to market earlier than some of you would like, but I can also say that it’s never done if we believe it would compromise an existing effort.
