All a facade, fights old men who are past it and smaller blokes. Hell even Usyk had to go through legal teams to enforce it as they knew it was a fight they didn't want. Fact is he has had all time in the world to grow some balls and go take the belt from Wilder and he didn't, Fury went on a bender, got fit again and jumped straight into it after a couple of tune ups.
The concept of "GateKeeper" is mental anyway, lot of Fury's career was in a totally different landscape to AJ, filled with similar fighters who were challenging Wlad for the title at the time. Chisora undefeated when he beat him, Hammer rank 3, Pianeta whilst not very good was a title challenger at one point so an adequate tune up. Wallin win is aging well after he beat Breazeale and i think he will do well against Whyte.
End of the day, AJ never went and took a belt, which is the essence of being a champion, he stepped up into a truly 50/50 style fight and got embarassed.
