To do this they would have had to add two two channel level controllers - one for the line level one for the headphone outputs - since the internal to DAC control happens before the DAC it can only affect both together. So that would have been two additional packages with attendant support components, with the additional power draw and space. Could have been done, there is probably enough space if they start to use the underside of the PCB a bit more. But eventually any design has to call "enough". There is more than enough remaining control capability in the controller chip however.
