This topic is about the ansible.builtin.oneline callback plugin, which is essentially deprecated and will eventually be removed from ansible-core. @utoddl created a thread (Mitigating deprecation of --one-line and associated callback plugin) on how to keep your own local copy and how to mitigate the missing --one-line parameter.
When reading the post, one of my first thought was “why not add the online to some collection like community.general?” That would make the plugin much easier to use for everyone, and I guess there are still quite a few users out there who like this plugin. This won’t help for the missing --one-line parameter, but at least you don’t have to keep around (and maintain) your own fork.
Adding it to community.general was my first thought since that collection tends to collect everything, and it is sufficiently maintained so that if something breaks in the future, it’s easy to get a fix in. Someone still has to fix it, though, but it’s a lot easier than if everyone has to fix their own copy of the plugin.
What do you think? Is there demand to keep the plugin in a collection, and which collection would be preferred? (If it’s added to community.general, also some tests need to be added. At least a few basic ones. So then it would have tests 
!) And if yes, to which collection should it be added?
