I don't think DGA members would be so angry. The biggest benefits in the WGA contract are especifically for writers (for example: the writers rooms).
WGA deal got 5%/4%/3.5% raises and 76% foreign residual increase, which are exactly the same than DGA.
The bonus for residuals (if a show get 20% of the streaming service audience) and a stronger protection from A.I. are the biggest advantage over DGA deal in issues they share. However, these benefits are mainly for long term. DGA will likely demand these benefits in its new contract in three years, since the WGA has set the precedent.
