The ability to do what? Give root ownership to a script? It is
unchanged. Once again: only root can change ownership.

In any case, the owner of the script is only security-relevant in two
cases: 1) if it allows someone to edit the script who normally couldn't,
or 2) if the script is setuid. Of course it could also change who can
*execute* the script, but if it's not setuid they'll be doing it as
themselves, not as the owner.

What exactly has changed?

Meaning you'll be running scripts as root, same as everyone. The only
difference is that you have to supply the root password to get there.
Once past that hurdle, the situation is exactly the same as using
setuid.
