Yes, you are asking for more functionality, but can I add this in a
follow-up commit please? I prefer this patch as is, as it can be
backported to stable branches and downstreams. Upstream a follow up
patch can add fields and more triggers which won't apply to any
downstreams.
This patch will help resolve a set of serious long-standing bugs,
see e.g.
