Many graduate students, faculty and post-docs are foreign citizens. So banning them from conducting research could potentially shut down big research projects. It is not surprising to me that the NIH and other funding agencies didn't want to do this. (It is also unsurprising to me that the current administration would have few qualms about disrupting research: we know they don't care, ask the cancer studies that had to be saved with private Foundation funding last year.)
Before you start throwing disruptive rules at projects, you generally want to know that there is a critical security concern for that specific work. Most research just gets published a few months later, so foreign interests can just read it in a journal and download the dataset.
