Looks like the tuition waiver is dead?

Via the New York Times (article by Alan Rappeport and Thomas Kaplan) (emphasis mine): 

The final bill adds back many of the prized tax breaks that were stripped by the House legislation, including allowing taxpayers to continue to deduct high out-of-pocket medical expenses and the interest paid on student loans. It will also continue allowing graduate students who receive tuition waivers to avoid paying taxes on that benefit. 

Good news for graduate students.

(Say, where the H-E-double-hockey-sticks did this provision come from? Who decided this particular clause would be a good idea? Shouldn't some enterprising reporter find the melon farmer distinguished gentleman or gentlelady that inserted this provision into the bill?)
