Because of the way defaults are handled and because of the sharing of
parameters this isn't easily possible. You don't know whether an option has
been set by the user or internally and so can't decide whether to set the
parameter or not, which implies you have to always set it, which then leads
to using default parameters that are suboptimal. Hence why I suggested
continuing an earlier discussion about presets for each codec.
