You mean that this would require a major/minor bump?  We're in the period
fter the bump that is officially declared unstable API time, plus those
functions are not supposed to be used outside of libav* as the Doxygen
explains:

 /**
  * Logs a generic warning message about a missing feature. This function is
  * intended to be used internally by Libav (libavcodec, libavformat, etc.)
  * only, and would normally not be used by applications.

I didn't make this up, don't shoot the messenger :)
