This doesn't handle devices with simply numbered outputs (such as many ICE1712-based devices), or cases where one PCM channel can be routed to multiple outputs. However, those devices typically have their own mixer applets, and generic applications aren't interested in configuring them.
As for routing more than one channel in the map from the same PCM, that seems a bit more complex. Maybe one could do a bitmap of channels instead of just one channel (with say, 32 room channel positions and 32 just numbered positions, that would be 64 bits). But how common is that anyway?
It's very common on the embedded side to use pure numbered stuff (or at least to assign semantics dynamically at runtime which I suspect boils down to the same thing here).
