Running only weekly just adds latency until PRs are created with no apparent
benefit. Multiple releases within a week for the same module happen rarely, so
it doesn't reduce the number of PRs.
For me personally, I receive notifications for the creation of the PRs anyways,
so the extra review request provides no benefit to me. I also asked the others
and they don't see a need either. Therefore, there's really no reason to
maintain this list here.
