I think the main reason is to support existing code using OSG and Qt4 on
their repositories.  However, I expect all distributions to begin
shipping OSG and Qt5 since Qt4 is fading away.

Personally I think that it would make sense.  You would usually file a
bug report against the OSG package.  For example, Debian has a
"wish-list" category for that kind of petitions.  You could also address
the maintainer personally.
