Are you saying that every Git command supports that option? I don't
think so.
And even those who do support it impose limitations when it's used.
For example,
$ git log file1 file2 ...
works, but
$ git log --follow file1 file2 ...
fails with an error message. So many important forensic
investigations limit you to single files when using --follow.

That's not guaranteed, because several files with similar contents can
dupe the heuristics.
Anyway, like Pedro said: the reasons for being in the "rather not"
camp are not strong.
