Why not?

It's not setuid, so being owned by root does not give it
any special privileges.

That's definitely a bad idea.  More so if it's writeable by its
owner, as is the case here.  It would mean that if a security
hole allows intruders to write to arbitrary files, then they
can overwrite this script and that would allow them to execute
arbitrary code.
