Nirvana did what all great bands do: they made everyone else catch up. Mainstream radio accommodated alternative music's idiosyncracies, in the case of Nirvana the confrontation of Cobain's distorted guitar, vocal roughness, sonic dissonance, and deliberately nonsensical lyrics. Whatever one's view of Cobain, it is undeniable that he set pop music on a new course.
In my mind the modern day version of the 'arrangement' is boy and girl meet each other based on the recommendation of family or friends, it could be in a somewhat chaperoned setting or on their own, depending on how open-minded the respective families are. Both parties are equally allowed a say in the matter.
