Your advocacy team can either build things - an SDK, sample apps, better reference docs - or publish things: posts, talks, videos. Both compete with the product roadmap for the same engineering time. How do you decide the split?
Decide by where developers are dropping out. Build when the blocker is inside the integration and repeats for every developer; publish when the blocker is awareness or a mental model. Then price the build option honestly, because an SDK is a permanent maintenance commitment, not a project.
