Whether you need a secondary set of release notes is almost purely a "marketing" decision, and should as much as possible be treated as such. Doing that is also usually way more effort (e.g. producing screenshots, etc.) than just writing plain release notes for a purse software engineer audience.

I think crafting good release notes (that go beyond automated release notes generated based on conventional commits, which are mostly good for bug hunting), is still a mainly manual and tedious process, though after the first few decent hand-crafted ones, the first draft can be handed off to an LLM these days.
