   1. Efficiency (One-Shot vs. Per-Patch): Unlike --cc-cmd, which runs
once per patch file, this runs once for the entire series. For a large
series or
      a slow script (like get_maintainer.pl), this is a  performance
win and avoids redundant processing.
   2. Dry-Run Integrity: By integrating it into send-email, the script
execution is part of the command's own logic. This ensures that
--dry-run
      accurately reflects exactly what the script produced within the
context of the mailing operation.
   3. Argument Deduplication: It eliminates the "Double-entry" problem
where you have to pass the patch list twice (once to the subshell and
once to git
      send-email). This reduces the chance of a typo causing you to
send patches to the wrong set of maintainers if the lists get out of
sync.
   4. Configuration Synergy: You can now set sendemail.cc =
./scripts/get_maintainer.pl in your .git/config. A shell wrapper can't
easily override or
      augment the built-in recipient logic as cleanly as this does.

That last point seems a clear win.
Far less maintainer annoyance at not receiving the entire patchset.
