Yes, this is true. I am enrolled in the IBR plan currently, which limits my payments to 10% of my AGI. Because I can lower my AGIby putting lots of money into my 457 account, I pay $200 a month for loans totalling more than $64,000.
The pros: it's cheap,and should get us to FI more quickly, as long as it works.
The cons: it's risky. Especially considering the new Presidential regime. I'm also totally stuck in my field for a whike, which would really suck if I ever started to hate my job.
