They could use OpenAI only as the natural language processing part, and constrain it to only using the vetted services/actions that Siri already can do rather than answering open-ended questions. That would still make Siri massively more useful than it is today since it would remove the need to word things in a specific way. It wouldn't be bullet-proof (there are always "jailbreaks" to these kinds of prompts) but it might be good enough if they slap a "beta" tag on it.
