I do not really see how you would benefit from having the source code for that wrapper.
- presumably in its current form it is not aware of devices and API-s which will become available in (say) 2012, so you could not learn "future compatibility" from it
- according to what you write, you would plan to integrate the wrapper on source code level into your code
-- it would result in code multiplication - your binary would contain the wrapper regardless of its presence on the device
-- and in fact it would result in lowered compatibility: even if a new version of the wrapper would be released, your particular application could not make use of it, because it would use the duplicated+obsolete version
