Hardly getting over it.
It could happen, anything can happen. But one of the reasons people hire expert opinions is to quantify the likelihood of something happening or, in other words, the risk profile.
However, establishing an expert opinion on something for which there is no precedent will invariably depend, however much it's dressed up in jargon, as much on the personal values that the "expert" brings to the question, as on the expert's knowledge.
