I'd be curious in hearing you elaborate on this. I've been in a WFH setup like this for about 4 months, and while I enjoy it right now I do wonder if it'll be something I might regret after 2-3 years on this schedule.
My primary reasons for working like this are that: 1. I hate being in the corporate office environment, it feels very artificial and constraining 2. I tend to have my most productive coding sessions very late at night anyway
My new situation is categorized as flexible office hours. I go into the office 2-3 days a week, enjoy good rapport with the people I work with, then WFH on Mondays and Fridays (typically). I find this to be a good balance - I have enough structure Tuesday to Thursday that I can continue this trend Monday and Friday.
