Even if not providing a groove the bass brings a depth to the music - think about guitar, having a “bedroom sound” that is full, with a depth to it live usually translates to rotten mush, it needs to be sharper to come through. At that point the bass is there, bringing the depth that’s needed, and in many genres providing that groove as well.
A good genre for that is Motown, remove the bass and even with those fantastic songs and great singers, well, not too sure myself.
