All this ignored, the problem is that applications can assume that they
can use e.g. the Main profile when they're linked to libfaac.

With your planned wrapper library this assumption would fail (and for
example the faac GStreamer plugin would advertise to be able to generate
Main profile while it really can't).

Why not just change the software you care about to use vo-aacenc? The
API of faac and vo-aacenc is not that difficult.
