Nice to see an open standard for this instead of proprietary integrations. Made a validator at ucptools.dev to help with implementation - checks the full spec compliance and tells you exactly what to fix. The /.well-known/ucp pattern is smart - same discovery mechanism as security.txt, apple-app-site-association, etc.
