I did this for a few months while I was transitioning back from parental leave and was similarly insanely productive. It just made me absolutely ruthless about prioritizing. Part of it was motivation to keep up with ft colleagues while knowing I had a hard deadline when I would be back on baby duty, so not sure how replicable it is now, but it was wild to go through a few workdays with all the day trimmed out, and then have a very full extended weekend with family every week.
But does ruthless prioritization mean you’re making other people do that work? You might feel more productive because you cut your day down to well defined tickets. But who is doing the dirty work to define the tickets, iterate with product, mentor and unblock other engineers, do on call, work on incident review actions etc etc.
