AJ there is an an interesting article on this very subject: https://www.hollywoodreporter.com/movies/movie-news/will-smith-career-damage-post-slap-hollywood-execs-weigh-in-1235122660/
from two top executives 2 different points of view:
Another longtime studio exec agrees there are still shoes to drop in how Smith manages going forward. If he could publicly reconcile with Chris Rock, for example, that might help bolster his image. But this top industry veteran is a bit more cautious, saying anyone casting Smith in a movie or series would have to weigh the challenge of trying to promote a project knowing that reporters inevitably would ask Smith and fellow castmembers about the incident. “I think [studios] would think twice — do they need the aggravation?” he says. “Everyone would do the equation, ‘I’ve got Will Smith, but now I’ve got this baggage and they’re going to reshow the slap. Do I need that, and is so-and-so available?’ The other side is, ‘I’ve got Will Smith, and he needs a comeback, and I’ll restore his luster.’ You would weigh factors — what the movie is, what the cost is.

He has been extra accommodating. And you read about what he did on the King Richard set.”
