How critical is the 15nH hf inductor for DCDC output

Hello Nordic Team,

in an application where space and cost is an issue: how cirtical do you estimate the 15nH inductor on the Output of the DCDC?  (L5 in nrF51x22 ref-design, L3 in nRF52810 ref-design)
Can it may be negliable, because of its low value compared to the 10uH inductor? I know, in the BOM you state the 15nH as high frequency chip inductor, but can you please specify its importance?

Kind regards
