What about where you're not just deleting a single entity by id? Like, for instance where a user can bulk select multiple items and then choose to delete them all (like email for instance), or maybe deleting by criteria, like "delete all Entities created before time X"
My gut says I would use query params though I typically stick with 1 action effects 1 record. I can't recall any specific times when I built bulk item management into an app but I'd say that's a personal preference on my end.
