--remove-background options currently not implemented?

[Perangelot]

--remove-background does not work for me, producing the following error code:

concurrent.futures.process._RemoteTraceback:
"""

The above exception was the direct cause of the following exception:

It seems to be irrespective of the pdf file I put in. I have installed ocrmypdf via `pip` because the arch package could not install; for some reason, `python-humanfriendly` could not be detected there.

From the release notes of v13.0.0:

The argument ``--remove-background`` is temporarily disabled while we search for an alternative to the Leptonica
implementation of this feature.

Is there an alternative or are there plans to implement this feature in the future?

[v4u6h4n]

Also interested, am a bit stuck about what to use an alternative to get rid of paper colour and texture.
