We could, but since past discussions and current testing have been
unable to justify preventing hotplug to a memoryless node in the first
place, I'm inclined to keep things simple.
If some edge case is discovered, making it conditional as you describe
will be a good solution.
Thanks for your review! A v2 of this set is pending my investigation of
Michael's suggestion to get node hotadd working.
