I have only worked on huge applications that take ages to spin up so bisect was never really an option.

I have not tried git switch thank you
I usually keep an improvements commit at the start of my branch which I `--amend` to while picking away at the task. If the commit gets too big I submit it separately, to be reviewed in isolation.
That's the best time to use bisect, set up a script to automate the build and test for the specific thing you're looking for, then use "git bisect auto ./foo.sh" and go to lunch.
