I've never done something like it but I'd assume there are lots and lots of gotchas with plans to deploy zero maintenance devices. It would make sense to me that nonzero, predictable, acceptable maintenance is better than a plan for zero maintenance which, if it fails, would leave you with more devices than you can possibly fix.
