The constant context changes, mental overload, inability to focus on one thing and do it well is exactly what every software developer has been fighting against for the past thirty years because it leads to shit quality and burns you out. You're automating the burnout. Idling is a necessity, not an illness.

Your feature branch is to put things aside and send them to CI, or wait and think on them. Not to have four of them running in parallel in your head frying you.

> What do you think feature branches are used for?

Yak driven development.
