IME it does deliver. Not necessarily directly (like, you're not going to come up with an action plan white meditating), but, over time, it helps cultivate a state of mind where those things are easier to do.

I think it does take time, though, like between 1 week and 1 month of daily practice, to start noticing the effects.

I agree, but I'll add that in my opinion a writing exercise such as OP describes is half-way meditation anyways.

different activities involve different degrees of mindfulness, and I believe making a sharp distinction, while sometimes useful, is usually harmful.

You can take a shit mindfully, way I see it. it might not be something you call 'meditation' most of the time, but I imagine it's even possible to do a proper meditative shit.
