I gotta disagree, I'm way more accepting of Scrabble list memorizers (even though I'll never be one) because word knowledge was intended by the game designers to be a part of the game.
Memorizing the spymaster layouts was almost certainly not intended by the designers of Codenames. Probably someone realized it was possible, but as other commenters mention the increased friction of fully randomized layouts isn't worth it when almost no one will want to do this.
