Peter,

If you don't like the script, please feel free to delete it.

Currently, no one is really maintaining (ie pushing patches to Linus) the
scripts directory.  Masahiro Yamada was doing it but has expressed several
times that he doesn't want to.  I got a kernel.org account, but clearly
haven't had time to figure out how to use it appropriately.  But simply
deleting a file is simple and risk free, so if you want to make the
change please go ahead.
