Sure. That's why I always play magic-users in classic D&D, too, because there's no magic that they can't use! (It's all in the name, after all.)No, but that's also a non-exhaustive list. The 1e PHB also says this under thief.
"Thieves are principally meant to take by cunning and stealth."
Cunning and stealth are meant for taking, because you can deceive someone into giving you their goods or into leaving goods open to your theft.
Crafty also means deceitful. You have to reach pretty deep to get to keen insight, which if you do, turns that ability into a god ability. You can have keen insight into.....................just about everything. Players should take cunning expert in all your game so that they always have an ability to use no matter what the situation.
Alternatively: as I already posted, the Cunning specialty is intended to capture a good chunk of classic thief abilities. You are the one who is trying to argue that it is an inapt word. I've refuted you. That's it.
