The Prebuilt-MPR only builds and updates a select group of packages. This is done for a few reasons:
- So the repository doesn’t get overloaded with package updates.
- So untrustworty, unpopular, or otherwise undesirable packages don’t get a PR to get added. In the scale of hundreds of packages, this reduces the amount of PRs that need to constantly be closed greatly.
If you want a package to be added then, you should submit a package request on GitHub for the package that you want added. You can submit a request for any package, even your own.
