Surely if reproducibility of .tar.gz files is the goal,"invoke whatever arbitrary binary on $PATH happens to be called gzip" is an poor solution. It is only even possible to consider stabilizing gzip output as a goal for Git (although this seems ill-advised for the reasons Brian already discussed) in the post-2.38 world where git is doing the gzipping. If one has the requirement to substitute one's own specific compressor, there is an option for that.
