What's more convenient, having to use a loop-through (current situation), or just plugging the card into the system and use it (with a mislabeled mixer...)? And since the bktr driver already has several configuration options it would just be one more, in case you want correct mixer labels. If you're satisfied with the current situation, fine. If you aren't, there's at least the possibility to try to get an improvement.
