With the advent of LLMs, data sovereignty is being bypassed. All three Service, Data, and Hardware sovereignty are important and should be the focus. It is not about prioritizing one over the other.
"Everything is highest priority" is the same as saying none of them are high priority. Considering one is a real issue we've already experienced, and others are theoretical ones we haven't, I feel like I agree with the current prioritization which is data migrations. Guess I'm too pragmatic to chase the ideal here, even though I'd want to eventually get to the ideal too of course.
