The point is to <i>avoid</i> the problem, rather than to stumble into a state from which it is difficult to restore the status quo ante.<p>Please do not mistake &quot;anticipating risks&quot; for &quot;fear of uncertainty and the unknown.&quot; This a risk for which the likelihood currently appears low, but the consequences could be grave and hard to reverse. At least to my mind, that warrants a bit of attention.
