Actually, there is a notable difference between the two. Replacing the
body of a package has a minimal impact on the database, but replacing
the header requires more work to invalidate cached stuff. I think
there's also a few other side effects.
This isn't to say that this is a good way to handle this, but I believe
it's why Oracle does it.
