NTC thermistor is always a good thing, especially if chosen correctly.
I had to use it a few times, especially when I had to design an off-line SMPS power supply.
The challenge is, the consumption has to be significant for a particular thermistor to cause it to heat up and drop the resistance, at the same time having sufficiently high resistance in the cold state to limit the inrush. This all goes to efficiency, as obviously there are extra losses associated with it.
Of course, with the radios we do not care much about efficiency

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
