Ah ok, I though you meant both versions.

Then I would rather drop 0.8 completely, otherwise it will be preferred
even with negative D_P from meta-multimedia (YOCTO #2964) and we cannot
expect people which happen to have meta-multimedia layer to know that
they are expected to update P_V everytime libav is updated in oe-core.
