I've had some further communication with upstream and they have agreed
that the libraries in question need to be unbundled, but may in the
meantime seek an exception. The reason for this is that the two
libraries are mainly used for serialization and they are concerned
that it may not work correctly/dependably across the different
versions of the library in different distro's. This is a summary, see
this link[1] for his full explanation.

I think part of their immediate hesitation is that this is apparently
an industrial grade app that has been used by Sony for use in movies
(such as Cloudy With A chance of Meatballs) and they want to make sure
it works the same on all platforms (the one big positive with bundled
libs).

They are looking into whether their patches have made it upstream or
not, so that's TBD.

Thanks,
