Closes #20230

You are on a roll @HypeMC. Thanks a lot for your contributions!

While merging, I added the versionadded directive (see 9f396ee), which must be included for the docs of any new feature. The pattern is:

.. versionadded:: X.Y

    The ...... option/feature/etc. was introduced in Symfony X.Y.

Thanks!
