I haven't deployed anything serious to ethereum mainnet and yet the stress of getting the command right and not messing up the private key or something is real, like no other deployment that I have ever experienced. I'm very curious how this will be solved (if ever), because no matter how good your process is, errors will happen, and boom! there goes your company/money/whatever.
