can't I request it myself?

Yes, you can.

However, the standard way to add new package to this bucket is creating package request before raising PR.

When creating a package request, you can check the criteria for a package to be accepted in this bucket. This can help you determine whether your PR is likely to be approved. The information provided in the issue can also help maintainers quickly get the necessary details.

PRs labeled package-request-needed are less likely to be reviewed and may be closed if there are no updates for a long time.
