There’s no free lunch and I’m suggesting the trade offs to support this are not worth it vs simpler approaches of doing a graceful drain & upgrade approach w/ a timeout for long running sessions if those may exist (+ if you have a lot of large state to migrate, it could be insanely long to complete an upgrade). This is because availability will never be 100% anyway in any scenario and this kind of transition can easily fit within your failure budget.
