What I mean is that if you're not a class which uses STR based weapons, have you ever put points in it to just for shoving and jumping (and carrying capacity)?
Do you think that buffing INT is going to make other classes start value it higher than for example DEX or CON as a second or tertiary stat, or is it just going to be a bonus for wizards (and to some degree arcane trickster rogues and eldritch knight fighters) who were going to up it anyway?
I think you have a point in that BG3 has made CHR less of a dump stat than what it traditionally is in the TTRPG by forcing you to use your main character for dialogues. IMO the best solution to this, and many other problems, would be to change the dialogue system to be more of a group effort, more along the lines of how you play real RPGs. E.g. if there's a medicine check it would make more sense to allow the person who's proficient in it have a go at it, rather than forcing the character who initiated the dialogue to do it.
But since we aren't getting that, perhaps the same method could be used to make INT more interesting? I.e. adding more skill checks for history, arcana, nature, investigation, etc. which have more impact on the game.
Also not a huge thing, but INT helps save against Illithid mind blasts
