And to add...
I think the best of both worlds is to be able to see the layers on the track the way we used to, just as we can do with envelopes being on the same track.
Lanes have allowed us to see envelopes on separated out (which I welcome and prefer), but we still have the original way (which has its uses but I rarely use now)
Lanes should allow us to see the audio layers in a similar way as an alternative, rather than the only way. I know some might not care too much, but imagine how you'd feel if you happen to prefer editing envelopes on a single track and were now forced to use automation lanes. Fortunately you have a choice there. I think we should have the same choice for audio clips -- it doesn't change the existing paradigm to do so.
