2022 X13 USB4 support still in the works?

So, the last update regarding this was in September 2023, which gave us access to a beta BIOS which enables USB4 support. However, the last BIOS revision I see at least for my XFlow 13 (GV301RE) is version 327, which was in August 2023.

Since then, there has been no official BIOS update and no USB4 support.

So I have 2 questions:

  1. For those who are currently using the beta BIOS (or used it in the past), were there any problems or issues? Did it work with G-Helper properly? And if you reverted back to the official BIOS after trying out the beta one, did you notice any changes?
  2. Has there been any word from Asus about whether they actually plan to officially implement this feature? All announcements of this model and several reviews mention the "upcoming USB4 support" but if Asus doesn't actually implement it, that's a pretty bad look imo.

Thanks for reading.
