They always required a license to reenter. The change is that if you launch intending to reenter you need the reentery license before launch. This is because Varda launched their reentry vehicle without a reentry license. Then once they tried to reenter the FAA balked because they had just assumed since the FAA had authorized their launch the reentry license was a given, which it isn’t. This led to Varda missing their window and scrambling to find a landing site for a while until they actually got their license and landed. This seems like a need for another regulation - the existing regulations left things ambiguous for Varda and that wasn’t good.
