I think that our regular repos will pick up the newer XLibre stuff; as of yesterday they did not, so instead I adopted the instructions provided by @Wallon to obtain the various XLibre packages directly from the XLibre source and I pinned those sources to 900 as opposed to 500 for other locations; the result was that I picked up the latest XLibre packages yesterday, and just to make sure the method worked I did it for both antiX and MX Linux and it worked for both without adding any systemD packaging requirements.
I think your approach assures the latest versions of XLibre as becomes available from the source. On antiX repo we do rely on @anticapitalista to update as often as possible.
