I refrained from weighing in back in July, but am intrigued enough now to chime in. While Tom D. gives his opinion and I cannot 100% say it is not 100% valid I have been involved with some aspects of the Report process from the perspective of the golf architects and their input to the USGA. I do not subscribe to the "conspiracy theory" that Tom D. feels is a delay tactic and, as he puts it, would be optimum to move forward during the COVID situation. But, his opinion counts...so I'll let him continue that feeling, of course.
My take is that between the R&A and the USGA they did have bonafide interruptions, and they simply could not see getting to a proper finish with COVID affecting many of their key people, not to mention the voices they needed to hear from outside their organizations.
Sure, this has been going on a long time but let us keep in mind that very little has been done pre-2000s at all. Nearly zilch, except for the various equipment standards which were pushed to the limit my manufacturers since Karsten Solheim began actually engineering golf clubs in the 1970s.
I remain hopeful and have a "glass full" perspective that good will come from the work. It is not as simple as many here claim. It is easy to sit back, log on, spout off and enter a keystroke or two. It is quite another to make informed decisions, back it up with data and a look at history and also to include all of the various players at stake. It is quite complicated if you take the time to dig deep.
