Are you aware of the downsides?

It stands to reason that not only Xerox had problems with JBIG2.

Thank you for the link, yes we are aware of this particular issue. For our engine we used only lossless mode and using this mode the decompressed binary image is identical to the original so the described problem cannot occur. Nonetheless this limit severely the usefulness of JBIG2.
