Does corrosion make them not effective?

All:

I've read the service life of copper-clad ground rods can last as much as 40
years depending on the type of soil they're in.

Be that as it may, I found some corrosion on 4 copper-clad ground rods that
are bonded to the tower and they've only been in the ground for 15 years.
The corrosion is light at a foot below grade, but I suspect it could be
worse down the length of the rod.

Replacing the rods isn't costly and it's worth knowing the grounds are in
good shape. The question is what to do with the existing rods?

Is there any benefit in placing the new rods near the old and bonding them
even though the spacing is close?
