I'm not aware that was ever the case, and if it was in 4.3BSD, I don't think that is the case in 5-FreeBSD. Unless a vm hacker tells me otherwise, I think 1.1 times RAM is a sufficient rule with one has 4-8GB RAM and no other reason to believe on needs more swap. 1.1 times is the space for crashdumps, and the need for that has already been told.
