yeah not a fan.

This only makes wizards more MAD in the sense of benefiting more from multiple stats which.

look, they don't need it.

IMO every stat should have some kind of benefit for every character beyond just impacting certain skills. As it stands, WIS, DEX, and CON are all important for the saves. CON and DEX give important bonuses to HP and initiative. CHA and WIS have important skills associated with them.

The ones out in the cold are literally just INT and STR. INT is pretty much only for lore skills which aren't that impactful, and strength is completely ignorable outside of Heavy Armor/Grappling builds which aren't that good anyway. Notably, even though athletics is really good its the only STR skill so its not hard to just take athletics prof and dump STR.

Here's what I would do.

Use more restrictive Carry Capacity
Use INT for initiative
