Recording multiple tracks was intended to be possible from day one. Many formats handle multiple tracks.

When it was pointed out that a lot of container formats couldn't handle increasing the number of channels mid-recording, we were left with two choices:
- Make the behavior dependent on container format (unpalatable)
- Make the behavior consistent, but not very useful (ie stop).
The WG chose the latter.

I am not aware of any change in the landscape of container formats that seems to indicate that varying the number of tracks is a generally available option. If you know of such changes, please provide references.

As for the "replace track" option - I don't think anyone thought about that possibility at the time.
