1. Nice, I think we all agree it's the best solution to give something back to the early-adoptors.
2. Good. There are just so many useful tools for a MVP-projects in your Startup-plan (and some in the Project-plan). You should move most, if not all of them to the Developer-plan. I just think it makes really sense for you to go for the Mixpanel and Stripe-approach of getting as many web products tighly integrated with you at the earliest time possible (at the MVP-stage).
Maybe it makes sense to limit integration in the short term (forces some people to go premium), but I think it'll be better for you in the long term to lower the bar of integrating with you. My experience is that once integrated with you, there is no turning back:)
