Yes the example shows this and that's why I'd keep it. Going further, I once had serious doubts about such quotings overlapping. Digged out a code:
gitout=( "${(@f)"$( "${gitcmd[@]}" )"}" )
Is it the same? Top-level quotes mark ${gitcmd[@]} as quoted, so splitting, etc. is done regardless of bottom quoting, but each quoting is kept separate and they don't interact when they are parsed?
