You're arguing edge cases with people who haven't even read the full article or understood it.Its not an edge case when the WIFI specification says what is valid and you should handle them properly, other OS provider's have designed for this and have successfully implemented these special cases. Apple did no follow the published specification, its a bug not an edge case
I agree it's not an edge case. If it's in the spec, it can't be an edge case. Some people don't understand the meaning of edge cases, probably for the same reason they didn't brain the article.
