Should be great if the plugin adds support to the incoming dependency management.
https://docs.gradle.org/nightly/userguide/platforms.html#sub:central-declaration-of-dependencies
The behavior I think that should be ideal:
it adds the version and the top of the file under [versions]
it adds the dependency without assigning it a name or adding the artifact id as name
artifactId = { group = "...", name = "...", version.ref = "..." }
