How will plugin dependencies be resolved after JCenter shutdown?

I’ve read an article about how JCenter shutdown influences Gradle.

However, it’s still not very clear to me how plugin dependencies will be resolved after JCenter finally closes. Could someone elaborate on that? Is going to proxy Maven Central?

The good news is that JCenter will apparently stay open indefinitely but only in read-only mode. That suggests that any plugins you are using right now which have not been updated will continue to work.

I am guessing they Gradle is still going ahead with this part:

Behind the scenes, the Gradle Plugin Portal uses JCenter to resolve dependencies of plugins. We will be migrating the Plugin Portal away from JCenter before the final shutdown. Builds will not need to make changes while the Plugin Portal migrates away from JCenter.
