What if, in 10 years, 1024-bit keys are factorable in <10 days on commodity hardware? I could call that a "breach of a single layer." If 1024-bit keys have been widely publicized, it turns into a "full breach", because the defenses weren't deep enough. If the keys had not been publicized, then the entire 1024-bit key space has to be iterated online in order to find weak keys. Now, of course the user can take some responsibility for not upgrading their key in 10 years, etc. I don't see why it's, like, some moral obligation to invite factoring attacks just because of the name of the key and knee-jerk hatred for "obscurity." Put another way, it makes sense to avoid pure obscurity when adding it takes extra work. In this case, GitHub is going out of their way to add theoretical weakness, but apparently we must do it, because security bible!
