Yeah for me that's one of the beauties of DayZ, and the lack of bandit skins won't change how I approach strangers anyhow, since right now "survivors" skinned people can still shoot a couple of innocents before they get the bandit skin anyhow, and often the tricky bastards use that to their advantage.
I will do the same thing I do now, watch and observe from a distance how they treat other they run into, if they are friendly to others then they are probably ok, if you see them kill others, then you know they are bandits whatever the skin.
One other thing I love about the mod is how it has made me explore and appreciate the scenery, it is nice that there are goods in every town, along with the Zeds, and I'm now getting to know each of the towns and areas which I've been playing on for a long time in Arma2 online MP, but never bothered to explore once the AO was cleared and I had to wait for transport to the next AO.
