They do get used. Been there done that.

Issues:

Linearity - not suitable for super fussy analog stuff, more suitable for amplification of digital signals.

Loss of Signal - With nothing applied they do have a high static current.

Differential - It's ground referenced not suitable CMRR. (There is a differential variation, but the CMRR is not super.

In reality they are complimentary signals not fully differential.
