For what it's worth, some of the new Parcel Fabric enhancements have been an absolute dream to work with, and I wouldn't go back to 2.9.x for anything. Our 2.9.x projects have all opened up in 3.0 without issue, and so far, none of our typical workflows or editing tools have failed to perform as expected.
That said, it's a perfectly reasonable approach to wait for the first patch, after the early adopters have found the bigger bugs.
