that's cool, but those chords aren't just arranged willy-nilly. the real knowledge is in the voice leading and arranging, not in the depth of chord names.

Oh that is so true. And that leads us to an answer to a similar question that's often asked about music theory: "How much music theory should I know?"
Without a knowledge of the companion minor (which is really just the relationship between a ii and V chord), tri-tone substitutions and IV of IV substitutions that blues wouldn't make any sense at all. But with that knowledge you can understand every single chord and why it works at that point in the song.
