This still misses the point. The best rogue(20 int) is still better than the best wizard(20 int) unless the wizard gets expertise. And in the skill that is quintessential wizard, but not at all roguish.
Intelligence has always been associated with the Rogue (and before that Thief) classes.
The 1E AD&D players handbook stated the Thief class needed a minimum of 9 Dexterity and that a "high intelligence is also desirable", intelligence being the only other ability mentioned besides Dexterity. The current Rogue gets proficiency in intel saves.
It is not as closely associated as it is to Wizards, and I understand your position, but it is false to imply it has not been traditionally associated with the Rogue.
Thieves in 1E were also the only class besides Magic-Users that could Read Magic, and the only class at all that could do it without a spell (although that was at a high level) and starting in 2E Rogues were the only class that could use any magic item, ignoring class, race and alignment restrictions (again at high level), something that continues with the current Thief subclass.
So it is incorrect to say Rogues have traditionally been tied to either intelligence or magic.
Wisdom is the traditional thematic "dump stat" for Rogues. Again going back to 1E, Thief was the only class in AD&D that could have less than a 6 Wisdom. If you rolled a 9 dexterity, 5 Wisdom and 18s in everything else you were going to play a very bad Thief.
