Well, it was a little more dangerous in v1.0 because of a bug that would make some ghouls attack you unprovoked, ruining your chances of finishing quests in Gecko. Jeremy Lowe: "There are three (in my experience) who do this: one of the ghouls in the first shack on the right as you enter the junkyard; a ghoul lurking behind the Harp bar (makes it very tricky to get into the plant); and a ghoul guard in the power plant - he's the one in the long corridor beside the entrance to the reactor core proper." Tim Weber chips in: "I don't know about the first two ghouls, but the last one, near the reactor core, will always attack me whenever I contact the Enclave on the computer. Other than that he just leaves me alone. (Unless of course I cause a meltdown, but that's hardly surprising.)" When I tested it myself the two nameless glowing ones in the reactor building would enter combat, and also the guard in the long corridor if I did the Enclave thing. The bug is caused by incorrect variable assignment, so there's no telling what will set off any particular ghoul.
