Google collections and Guava both bundled, package exported without version

I noticed today that FECRU is bundled both google-collections 1.0 and guava r06 in the lib directory. To plugins, FECRU is exporting com.google.

as version 1.0, but com.google.

without versions. Is there a reason to bundle both the older google-collections and guava libs? Can we please please please specify versions for everything that is exported? In the case of guava, since the version is r06, the exported package version should be 6.0.0.
