The plan is to expose some mechanism to support tags. Unlike, cloudflared, many of the user desired tags can be populated automatically from ingress spec information (host, service, port, etc.). Attempting to specify information as part of an annotation would force users back into a one ingres-per-spec situation (which is not acceptable).
Cloudflared supports marking tunnels with user defined tags. Sometimes, these tags are not just metadata, but feature enable flags under the covers.
