The code in question mostly predates the spec and has been extrapolated from this expression of Hixie's opinion at one point in time:
http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2006-October/007430.html

I thought the spec at least at some point banned empty rows. Am I mistaken or has the spec changed?

Why aren't empty rows banned? Not banning <ul></ul> makes sense, but once you have <table><tr></tr></table>, you might as well require it to be <table><tr><td></td></tr></table>, since this requirement isn't more substantially more onerous to authoring tools but helps catch unintentionally empty rows.
