Who is talking about that? If you think that is what skill 0 means, then sure. I don't think that is what skill 0 means. But if you want it to, you can make it that way, but you pretty much have to completely rewrite the Character generation system. Because it is designed to primarily produce characters in the skill 0-2 range.
Going by Chargen, there's no likelihood that anyone is even rated as an Engineer until their 2nd term, if that. Everyone in Engineering term 1 is busy as a mechanic on the maintenance crew. Is it even possible to have Engineering 0 outside of the cascade system effect? I'd have to look to see if the scouts or merchants have Engineering as a service skill.
