I work for a firm that does things like ADCs, DACs, amplifiers, power regulators, power control parts and RF parts. We also do some SoCs of various sorts. In those markets it is often hard to justify even using 40nm. A lot of development is still on 180nm. The masks are cheap and the turnaround is quick. They're well understood and free of mysterious yield problems. The on-chip analogue components such as bipolar transistors and capacitors work well.

To us the processes that even come close to state-of-the-art are something specialized to be wheeled out for very specific problems.
