What problem would that solve?

In data formats like WAV the sample rate is stored inside.
In audio processors like plugins the sample rate is passed out of 
band.

If you pass the sample rate along with the audio data, then 
you'll have to support the hypothetical case where it would 
change every buffer. Hence why out-of-band is often preferred.
