@ipmb Hi! Do you have metrics as to what proportion of your users are using the legacy heroku/buildpacks:* images (vs the heroku/builder:* images)? We had been planning on making the heroku/buildpacks repo private at some point to prevent people unknowingly using an insecure image (it hasn't had security updates since May 2024), but wouldn't want that to cause too much disruption to you/your users.
