PSLF is not an alternative to REPAYE. PSLF is a separate entity whereby if you are employed in a qualifying job and make 10 years worth of payments under a plan like REPAYE/PAYE/IBR, your remaining balance is forgiven.
The question being discussed above is more whether to stick with minimum payments for 10 years under REPAYE/IBR/PAYE, which for many of us with high debt (yourself included) would result in our debt totals continuing to climb because the minimum payments will not be enough to decrease our principle OR to remain enrolled in the income-based plans while paying more than the minimum, thus servicing the debt and potentially leaving money on the table if PSLF remains intact.
As to the question of whether or not people have actually have had their loans forgiven, I've seen rumors on reddit but nothing documented. I know white coat investor is looking actively for people whose loans have been forgiven for real and planning to write something up on his website when (if) he finds them, but I don't think we have any hard proof yet.
