I'll take the first stab at reviewing what happened in the hope others will chime in with what I don't remember or left out.Interesting points raised about the potential non-conforming equipment hypocrisy/dilemma. I think the wedge groove/anchor putter/driver size rulings all came down during my 19 year golf hiatus and I don't know how long weekend warriors resisted or how long the old stuff was grandfathered. I know a few who haven't acquiesced to those rulings yet but the vast majority had already by the time I returned to golf and I think 'social pressures' probably drove the conversion...
First off, the USGA and R&A never outlawed the long putter and belly putters. Instead, they instituted a new rule on how you can and can't hold the putter. They called this the anchoring ban. This is not actually accurate as there are several ways you can hold the putter that creates anchor points, as any mechanical engineer will recognize. But they did outlaw 'some' forms of anchoring. There are still players who use these putters, but not nearly as many. Most manufacturers stopped producing these putters, and those that still do are mostly in the intermediate length that used to be called belly putters. As far as the new rule, first they proposed the new rule and gave a comment period. Then they approved the new rule to be effective at the beginning of the next calendar year.
On the other two, they didn't grandfather anything. Instead, they created effective dates as follows.
For the wedge groove equipment change professionals made that change effective the beginning of the next calendar year. So, the pros had a short period of time to try out new conforming equipment and put it in play. Then they phased in the new groove requirements for other layers of players and competition. As I recall, amateurs like us had about 3 years to change out our wedges, unless you played in some USGA amateur events. What was interesting is that in the very first year, the PGA Tour professionals had to use wedges with the new groove rule all the wedge-related stats showed it didn't make any statistical difference in their performance, which was the whole point in doing this.
I'm most fuzzy on the driver head size rule. My recollection is they proposed a new 460cc maximum head size rule and then implemented it fairly quickly. Most drivers were still at 460cc or less, but the trend was bigger and bigger heads, so the ruling bodies were trying to head this one off at the pass (pun intended).
