It's actually an implicit assumption of the model Josh threw out if you
stare at the numbers. The settings for work_mem are twice as high per
connection in the Web+OLTP application cases, based on the assumption that
you're just not going to get everybody doing sorting at once in those
situations. I toyed with exposing that as an explicit "connection load
duty factor", then remembered I was trying to deliver something rather
than tweak the parameters forever. It may be a bit too aggressive as
written right now in those cases.
