Their APIs are garbage from an agentic perspective. Try using Terraform to curate your GH org of a few hundred repos. Just running the `tf plan` will take 10min, because it's making thousands of API calls. Where's the bulk and batch APIs? No such thing. They are simply not agentic scale. Want to rerun the plan for your entire cloud vendor with thousands of VMs, IAM roles, buckets, etc... it'll run faster than checking on your repo labels.
GH needs rewritten from the ground up. The "repo is everything" arch has been creaking and falling over form many years now.
