given how stagnant the galaxy is before humans entered the scene (all other races were taking it veeeeeeery slowly according to the background info in the games and that humans were doing things alarmingly fast compared to the others) i think it never crossed anybody's mind to even explore bekenstein's part of space. or maybe they did, but the expedition got sidetracked and never followed up due to some series of unfortunate events.

it's also mentioned that turians have the ability to map huge swathes of space with groundbased telescopic arrays. if they had that ability it's no stretch to assume every other citadel race also have it. what kind of fluke must there be for not applying that sort of technology into scanning the widow nebula's vicinity for potential colonization/resourcing sites? a staggering lack of curiosity/imagination? well, nobody bothered to analyze keepers until chorban, what does that tell us about the mindset of other species.

whatever happened, however unlikely the explanation/s, bekenstein being human territory was what we got. note that boltzmann and all its planets were named according to human conventions, implying it was first claimed by humans and nobody else. we never hear of anyone contesting the claims anyway.
