That is always the problem with this fight, yes. In a sense it's a meta-GAN, with other teams building better discriminators that can then be used to further train the generator. This works 'out of the box' if the discriminator is differentiable, but even if that's not the case you could use Reinforcement Learning to achieve the same, I suppose. If you have the man power, you could even train humans to spot deepfakes and then use them as discriminators to improve the fakes in turn... yay!
