Is Bootstrap 5 Compulsory in 3.7.0 or Experimental

I fear this will most definitely break all of my projects that I update. Is the new BS5 beta version integration in Wappler optional under experimental features or there is no way out? The update post does not mention anything, so I think its compulsory.

Also, is there a benefit to BS5 over BS4 besides no jQuery dependency? Would really appreciate if someone can share a link or some insight on this.
