It takes even less seconds to add one line of code that prevents that.
That excuse stopped being valid when more and more powercreep was put in the Wilderness.
People can't opt out of dpick. People can't opt out of MA2 Cape. Chaos altar, black chins, old revs, how can someone afford to opt out of those and still be on the same level as other players?
Whilst I'm not disagreeing with any of the other points you've raised, I really don't see why leaving stars within the Wilderness is a problem. There will always be another location on another world if you're not interesting in going for the Wilderness ones.
