Problem to solve

For a large repository, Renovate may rebase a lot of pull requests. It affects developer experience, for example, a lot of queued jobs are stuck in CI.

How to solve

It would be nice if Renovate supports the schedule to limit the schedule of rebase. For example,

{
  "rebaseWhen": "conflicted",
  "rebaseSchedule": "before 6am"
}
