Unable to remove campaign admin with composer replace after upgrade to 4.8.0

I was able to remove Campaign Admin fully with recipe-cms 4.7.3 using the following in my composer.json:

"replace": {
        "silverstripe/campaign-admin": "*"

However since the upgrade to 4.8.0 I am getting composer errors with this block in my composer.json.

Is it still possible to remove campaign admin completely in 4.8.0?

Replacing “*” with “^1.8.0” seems to work
