Yup, the entire world has accepted it other than a few Mosconi nut huggers. Funny, I still think Mosconi was the best that ever was and I have an autographed pic of him by my pool table at home.
Cal Ripken broke Lou Gehrig's record of most consecutive games played, over 14 years playing without missing a game. It takes skill to do it that long without being benched, ever, and you need dedication to keep playing almost every day even in the dog days of summers, playing with numerous bumps and bruises. And you need to be lucky, to never break something or have an injury serious enough to keep you out of the line up. And mental toughness as you closed in on the record.
Cal breaking the record did NOT diminish Gehrig's career in the least. And nobody, not Cal himself, will tell you he was a better player than Gehrig. And I'd better a million bucks JS does not believe himself better or even equal to Mosconi. So, not really sure what the concern is.
Most sports cherish their world records, ensuring their legitimacy and in appropriate cases measuring them to the nano-second.
But pool, not so much. You set up a table so gaffed-up it's not even part of the regular pool room inventory and then quickly disassemble it after the record and cart it away. And you make sure the conditions are so ideal they don't resemble anything else anywhere in the sport. You have the record certified by two guys at your governing body who, by all reports, don't even play the game, so that "it's official." And then you make sure to never let the unedited video leave your safety deposit box.
