I agree with everything, but wouldn't it be better to go for a "softer"
strategy such as:
1) remove the old scaler interface first (as far as I remember, we
    just need to increase the lavc version)
2) after that, make swscale the default, having a "--disable-swscale"
    switch for enabling the old scaler. When such option is selected,
    it prints something like "WARNING! On 2009/1/1, the old scaler will
    be selected, and this option will be removed" (2009/1/1 is just an
3) on 2009/1/1, remove the scaler

After all, the two scaler coexisted in ffmpeg for a long time: waiting
2 or 3 more months  should not be a problem ;-)
And in this way people will be warned in advance...
Just an idea.
