Wisdom is literally one of the big three stats for the most common saving throws, and completely dumping wis means that you'll be lucky to save out of spell effects thrown at you, but sure, it's roleplay garbage.
But that's not really related to the onednd stuff, they didn't change the way ability scores affect your character, and given that they were into refining classes before WotC went quiet, it's unlikely that ability scores will get changed now.
