Yes, that's the current discussion.
Safrole (aka: 3,4-methylenedioxyallylbenzene) is still the primary starting precursor for clandestine production of MDP-2-P (aka: PMK), which is then reduced to MDx (usually MDMA, but it's also possible to make MDA, MDE, et al.). However, it is far from being the only chemical through which MDMA can be produced, some much easier and more efficient than others, but multiple ways still exist is the point as do multiple starting points. Because of the crackdown on sassafras oil and Safrole, clandestine manufacturers have sought and devised new methods to avoid unwanted scrutiny from law enforcement. New methods produce synthesis-specific side-products that LE analyze to reverse engineer the synthetic method used by the chemist to investigate who they might be, how they're producing the drug, where they're procuring their chemicals, and what new precursors need to be watched, controlled, and/or reported on by distributors.
So it's a game of cat & mouse… you know, pop goes the weasel & all that shiz.
