Using a HEX editor and changing binary code, yes. But that is not very
likely to happen as it is quite difficult. A script, on the other hand, is
plain text and easy to modify. So I think the reason here is simply that
as scripts are so very easy to modify, at least keep their permissions as
limiting as possible. Don't just leave the key under the mat.

There are those (myself included) that think that SUID anything is bad
design. We no longer use it in our code.
