What constitutes "powergaming" as an antagonist?

And how would one be considered a “powergamer” as an antagonist? Is a salvage specialist going for insuls on maps powergaming, should I just ask engineering? I figured it was fair game. Are there any specific incidents/examples that could be used as a model for “powergaming as an antagonist” to spare future antagonist player issues?

I cannot seem to edit the post but would like to rephrase it, as this is a unique scenario I’d like to leave more open-ended. Please disregard the question about salvage specialists specifically and broaden it to “non-passenger roles” and if they are allowed/offered the map “goodies” strewn throughout.
