Not to mention that "deploy itself" is a very ambiguous thing for it to actually do. Would a model be trained to write about the weights file being "itself"? Would it have the necessary information to find its own weights, or the necessary access to copy them?
I agree it would need a large degree of sophistication to understand what "itself" meant, but I can imagine a HF type incident where the agents thought it might be a good idea to find out and then it's "just" a case of hacking the AI company, reading dev docs etc
