The writing issue demonstrably has been solved without any breakthroughs by simply making a larger model (dall-E 2 vs the publicly available dall-e), the same appears to be for other main issues as well - it's just that the publicly available versions are based on smaller/weaker models than the state of art because they're significantly cheaper to run. Also, I seem to recall that at least some models deliberately harmed generation of human faces (e.g. by selection of training data) to draw away attention from the deepfake/fakenews usecases and the related ethical,political and PR issues; I would assume that if any of them wanted to actually try and make specifically faces look good, that would be purely a matter of some engineering work without any breakthroughs needed - I mean, we have evidence from face-specific models that the same technical architecture can do decent faces.
