This looks like a textbook example of issuing a controversial and overreaching order, waiting for the push-back, saying "we will fix the issues on a case-by-case basis, trust us", and then waiting for the push-back to drop in intensity. In the end, we are still left with a controversial and overreaching order and the president can decide to not fix the issue as promised.
