I don't have an inrush limiter on supplies with smaller capacitors, but when you're adding 5,000uf to 10,000uf of capacitance, it makes a bit more sense to knock down the big charging spike. For instance, for my YLB - RailSounds Battery Replacement, I have to charge the 1.5F supercap from a 5V supply. For that application, I added a 10 ohm resistor to limit the inrush current to a reasonable 1/2A or less.
