It's been floating around the last week that Congress is looking into it.
Like you said it would be ridiculous if they did it. People aren't saving enough for retirement, and they are also floating reduced Social Security benefits, and they propose this?
I don't think it will go through, but the fact that they are even considering it is disturbing. It's much easier to max out your 401k pretax than post-tax. Learned that when I switched from Roth 401k to Traditional 401k a couple of years ago.
