Bootstrap has 98% of utility classes that you need for most projects. And if you use a design system or one of their themes, than the only 2% of css you have to modify is the color pallet and a few extra classes to cover edge cases.

Reinventing the wheel by subdividing all of your css into individual classes and combining them in html again just doesn't seem like a step forward to me.

Including responsive classes? i.e. make this div X rem on mobile, Y rem on tablets, and Z rem on desktop? With 3 class attributes that require no config?

Yes

Bootstrap also comes with a hole bunch of unnecessary components.
