I’ve uploaded a new plugin “org.embulk.embulk-plugins” last week, but that is still pending.
IIUC, if the plugin’s “pluginBundle” does not have a “mavenCoordinates” block, its Maven group will be prefixed by “gradle.plugin”, and it should be “approved automatically”.

The plugin actually does not have “mavenCoordinates”, but it does not look approved automatically, and still pending.
Can you have a look?
