Folks resist change---especially us seniors. I don't have a problem of taking a couple of executive courses and making 6" golf holes. The head of PGA has suggested a 15" hole as an experiment to speed up play. Big difference between a 6" hole and a 15" hole.
Current size is 4.25" so making a golf hole 6" isn't making it all that much bigger. I don't see it as a big deal at all---my bet is that some putts will still be missed.
