Thanks - glad it matches the use case you had in mind.
For review, the PR is already open and linked from this topic. I don’t think there’s a separate public review-request route available to me, so the most useful thing is probably for people who would actually use it to add a reaction or a short comment on the PR confirming the use case. I’d rather not repeatedly ping individual staff members.
It could be packaged as a separate plugin, although it wouldn’t be completely trivial. The implementation is already entirely within the bundled events plugin, but it changes the existing scheduled event-date rollover path as well as adding the successor-topic service. An external plugin would therefore need to hook into or override that part of events, which would be more brittle across upstream changes.
So my preference would be to see whether the upstream PR is accepted first. If it isn’t, or it looks likely to remain unmerged for a long time, extracting it into a separate plugin would be a possible fallback.
