I'm highly aware of which branch I'm on. Because it's because I don't use any scripts or automation that switches branches; I only ever switch branches manually so I have that awareness.
For example, I don’t expect running scripts/build.sh to modify tracked files in the repo. Seeing part of the prompt go from “” to “?2!3” (two untracked, three changed files) makes that glaringly obvious.
And the Branch is also an unintrusive reminder that you are in a path under versioncontrol.
