Stateless systems aren't difficult. The load balancer need not route to nodes with updating services. It is possible to design code that can update without restarts, but few developers are industrious enough to make it a priority. Evidently, the trickier and more difficult a specification is, the less likely a developer is enthusiastic about providing it.[1] [1] https://i.imgflip.com/1rug8x.gif https://i.imgflip.com/1rug8x.gif
