Yes, I was referring to your posted schematic, which is typical for single-supply operation of op-amps. (I was looking for a typical circuit and saw yours, but hastily referred to it as the OP's.) PSRR of single-supply circuits, including bias chains, is an important design consideration. I was involved in a re-design of a system with over a thousand dual-rail op-amps at the end of long power distribution wiring, and we had to add point-of-load regulators to avoid cross-talk from one end of the chain to the other due to power supply impedance. (This was due to the PSRR of the op-amps themselves, and the class-B output stages pulling relatively large currents from the supply at high output voltage, thus affecting the voltage at other amplifiers far away, resulting in non-local crosstalk.)
