The oss.sonatype repository is being sunset and maven.pkg.jetbrains.space is as well. The best way to future-proof is to accept generic repository and username/password and make all the changes in TC deployments instead of the publishing code.

The change in kotlinx.coroutines was made to showcase what needs to be done for other kotlinx libraries. We will now publish to Space packages and then relay from it to Central via a dedicated deployment.
