Headers are read by nobody unless a client library surfaces them, and few do. The effective mechanisms are the ones with human contact: e-mail to registered developers, changelog entries, and finally breaking the endpoint in a staging environment first. I would present headers as good hygiene that supports the process, not as the mechanism that makes deprecation work.
