Starting at this year's Roland-Garros, all four Grand Slams will use a 10 point tie-break to decide final sets when the score reaches six games all.

Honestly the 12-12 TB is ideal. Gives more than sufficient chances to break and leads to potential for classic matches (2008 W F, 2018 W SF, 2019 W F, 2013 FO SF all ended before 12-12 or happened with the 12-12 rule), but cancels out the chance for servebots to play like 8 hour matches. 6-6 is sorta anticlimactic
 
Wimbledon soon threw out the "12-12 strikes the right balance between traditional final sets and stopping 70-68 and 26-24 scores". I thought they were in competition with the Australian Open over this as well? As all 4 are now developing the 2019 Australian Open model, I'd say Wimbledon lost.

Even a 2019 Wimbledon final experience is out now. That Djokovic vs. Federer final was one of only two matches where the 13-12 fifth set happened at Wimbledon, the other one being the 2021 first round match between Oscar Otte and Arthur Rinderknech.
