That's great feedback though: We'll add a new page to the website for each package that provides the snippet you can run on an RDS instance to load the extension and then run `create extension`.
We're also in talks with RDS team and experimenting with a few options that would allow users to query the registry directly. The most promising one we have found so far is using AWS Lambda with RDS's aws_lambda extension to do that http part, and pass the contents back to the database. Still a WIP though!
RDS has a strict list of approved extensions. (Since AWS is on the hook for the system stability, security, replication, etc.)
