My model was that this is the thing going on for many night owls. I believe I had studies at one point that would back this up, but could not immediately find them.
if you benefit from a visual indication of wake time blacking out the external light and replacing it with light under your control seems much better, if you can get it bright enough?
I’m not in principle opposed. The approach you mention has super conceptual benefits under the model you and I share. In practice, I find my friends often have lights that go from zero to very bright very fast. I expect this to be more equivalent to an alarm clock than a subtle nudge to your sleep cycle mechanism to start moving towards wake-up-land.
