@yohannpoli I'm aware of this as it has also been a warning for many other android libraries throughout the year 2019.

I don't think the removal will affect any given library unless the main Gradle version used on your app (the one making use of these dependencies) gets bumped to the latest major where this code gets actually removed.

I'll make a PR with the changes.
