I hear you, but the thing is, what do you achieve by "cramming" more "doing" in? Do you also switch to those nutrient rich powder meals to save an extra hour or two prepping and eating food too?

Are not all of those things that could be optimized away an opportunity to let yourself feel, relax and simply be?

The examples you bring up (like waking early to do something for someone you care about) has nothing to do with the topic of engineering for consistently reduced sleep, imho.
