LTC1778 maximum inductor value

What is the largest practical inductor value (10uH, 100uH) to be used with the LTC1778, specifically when used with light loads (10mA to 250mA)? I understand that the LTC1778 will drop back into discontinuous mode with light loads but has anyone studied what the threshold of inductor size is where the LTC1778 can no longer regulate or operate within an SOA, given that a larger inductor value will likely yield higher self-induced transient voltages, which may exceed the absolute maximum ratings of the LTC1778 (36V). Is there any issue with using a snubber network from SW to GND to dampen such transients, should they occur, when using an inductor greater than 22uH?
