With the exception of like, binary patching of executables that use versioned symbols or some craziness like that, virtually all software cannot be upgraded while it is running and expected not to produce errors. I mean, if you use a plug-in style system, you can program it to block operations while a module is reloaded or something. But most software is not designed this way. Especially with ancient monolithic models like Go programs. Upgrades just can't be done easily in a complex system. You can do them without concern for their consequences, but that doesn't mean they're safe or reliable methods.
