While I agree that the wake-up feature you described is not available from Apple directly, I bet there's a 3rd party app out there that does what you're asking.

I use the Apple alarm now and when if I go to sleep with my watch on, it will gently buzz on my wrist and get more forceful until I turn it off. The sensors to track sleep are all on the device, but Apple doesn't seem to have any interest in building a "sleep cycle" tracker at this time for whatever reason.

A cursory search turns up the "Sleep Cycle" app[0] with a ton of reviews and even an "Editors Choice" award. Maybe Apple is holding their horses until they 100% nail the implementation, but if you can live with 90% in the meantime, it would probably be worth it to you if this is a thing you're really wanting in your morning routine.
