I'd guess they have not been keeping up or were just deluded as to the "knowables" and "unknowables" right now.
I would think that unless you had the means to fight it legally--should she be detained or denied entry--that I would not take the chance.
And yes, I read the two comments upstream telling you not to listen to anything on DU. While I agree that no one here is likely to be an immigration lawyer, I think you realize that even THEY can not be certain right now or you would not be asking. I DO agree with the premise that those documented immigrants will likely take a while to get to (if ever). That said, there ARE going to be MISTAKES MADE and correcting those mistakes for someone who should not have been swept up or disallowed entry are unlikely to be immediate or without undue difficulty.
At a minimum, you might want to let this shake out over the next couple of years. There will be an entire team of ACLU and other lawyers fighting the early efforts and so some of those early court decisions will likely bring both clarity (and hopefully) some boundaries for TSF.
