Looks like PA design is in higher demand or is harder than other designs. Do you think so?
yes, the PA is the most expensive component, and the bottleneck for linearity, distortions, and are easily to self-oscillate, and is the most power consumption.
Also, the other components are available in mass produced ICs.
