1) the removal of OpenGTL mid-stream breaking user or other apps
(and we can't truly remove it anyway - it stays in the F20 release repo)

This may be solvable by use of the patch mentioned elsewhere in this thread.

2) as the policy is to not update ABI on libraries, it requires an
exception. Concerns would be about the number of apps affected, coordinating
the release of all dependent apps, how likely user/other apps might be
broken by this ABI update.
