Thanks for the extra information. From what you're saying (and the information I've received separately from the nominator), I think there are worldbuilding tags that could be nominated (e.g. about the fictional suburb specifically) but the ones currently awaiting approval are rather too broad for such a close-to-real-world canon and would be almost entirely on the "historical research" end of the spectrum. As such, I'm not going to reject the fandom outright, but I won't approve it unless the nominated tags are altered.
