Incorrect. I'm a second voice who will say that it makes being a gm much more work for me and I'll bring examples.
In another thread I was arguing with someone about how 5e's meaningless AoA structure complicates certain types of encounters when they said that 4e had the same AoO rules that allow you to run circles around a monster without an AoO. After pointing out the shift and walk actions they admitted that they either forgot or were playing it wrong without noticing. Do even though a variant rule of "you could optionally choose to remove opportunity attacks for moving from one threatened square to another" would accomplish 5e AoOs I as a gm need to design much more complex encounters with many more baddies if I don't want my pcs to simply walk past the guards and nooks to gank the bbeg they work for
