“Moetzes Gedolai Torah issued a public statement, which decreed that the Vort ceremony be COMPLETELY ELIMINATED”
In my small knowledge just based on what I’ve seen, the Litvish minhag has been for years not to do a vort and to just halachically not be engaged until 2 seconds before the wedding. Chassidim don’t do like this. From what I’ve seen, the people still doing vorts have a minhag to do so and I’m not sure anyone really would say they should be mevatel it. The public statement you mention was probably just to make people feel better about following the former minhag.
