Do y'all think CM Punk's ufc career is considered canon in WWE like Brock Lesnar's is in kayfabe? How does the UFC exist within the WWE?

Also how does WWE coexist with other combat sports? We all know boxing is canon with Fury and Mayweather. But how does The UFC operate? Is it like viewed on the same level it like a lesser competitor since Brock Lesnar's and Ronda Rousey's MMA careers are one of their most prized achievements in their respective tale of the tapes.

CM punk obviusly wasn't as successful but could they blame it on a bad weight cut? I like these conversations about kayfabe lmao
