I wonder how much of this was driven by public/media interest in the H-1B program rather than technical policy concerns.
For instance, there is still no action taken about the L-1B visa classification, which is a lot more open to abuse than H-1B is. It has no cap on how many visas can be issued every year. It also has no obligation to pay the employee a prevailing wage, no requirement for a bachelor's degree to qualify, and it cannot be transferred to a different employer (which means employees are stuck with their sponsor until they qualify for a green card).
