Well more importantly, and this doesn't get nearly enough coverage, #Title42 is a section of law with specific requirements for how it can and cannot be applied.
It's not merely up to the discretion of an administration. The president doesn't get to just use it whenever he feels like it, and presidents don't get to go back and forth on the law as they come in to office.
Title 42 is no longer legally available to the president, so it's really been something to hear Republicans demanding that it be kept around, when that goes against the law itself.
