I wonder how that would translate into 5E... I never played Pathfinder and 3.5 for one a few months over 10 years ago.

Poorly. It was a patch on the multiclassing system, designed to make cleric/wizards viable in a system that had significant issues with it due, among other things, to the number of mechanics tied to caster level (especially spell resistance). 5e simply doesn't need to patch that; it's designed with multiclassed casters in mind.
