A few thoughts:

1. Cloudflare has an unusual structure in that we have a three engineering groups: the core engineering group that builds things that the product management team specify, a totally separate disruption group that works on riskier bets, and a crypto research group.

2. I strongly believe that letting people work in languages they love has a huge advantage. Engineers want to learn new skills (and those that don't we don't want to hire) and so letting them do that means they are happier and do better work.

3. Small teams do more than large ones. The teams that work on Cloudflare products are very small and agile.
