Once you've got AC coupled video, then having mean level AGC doesn't make things much worse. On -ve modulation it's dead easy to do sync tip AGC so there's no real economy in adopting mean level AGC.
One other point about AC coupling and mean level AGC is that they reduce the variation in EHT current. Hence EHT regulation can be worse without causing objectionable changes in picture size with content.
