I think you might be talking about the sierra.c (which was actually
cloned from the airprime.c driver)?
In a perfect world I agree, it would be great to unify the drivers.
However Sierra is slowly but surely adding more and more proprietary
feature support (e.g., USB vendor specific commands, change in end-point
support, etc.). Granted this still could all be maintained in a single
driver it will likely get _very_ ugly.

This is not to say we shouldn't encourage collaboration with each other,
esp. with throughput issues, those will likely affect all drivers
