hey cofounder of cal.com here. the plan has always been to: 1. start and go fast with a mono repo and trpc fullstack api to understand and learn the fastest. once we knew what we need, we were able to build an external facing API. we wanted to be very clear to externals that using our “trpc api” is with caution due to undocumented breaking changes. a lot of companies have an internal API + external API (built later)
