Wasn't original reason for this in telecom industry?  AFAIK u/a-laws were invented to provide better dynamic range of phone conversation, because all you have in there is 8 bits. It was better idea than stealing 2 slots for one channel, reducing throughput by half.

These days, memory and precision are not a challenge. So, if you still want the grunginess of variable quantization, just bake it into the samples.
