That would be a dumb product decision to make. Nest Protect complains about the smallest things, from connectivity (which does not affect detection, by the way), to battery, to positioning, and so far I have been reliably notified in the app. On the other hand, I did have plain smoke detectors before my Nest ones, and at least one was completely dead for a year without no one knowing.
