What slack are we supposed to give here? Which tight restriction are we supposed to relax? We know the neighbourhood stars and we calculate the closest supernova candidate is at a distance that will permit the attenuation of its explosion emissions to levels below "damaging" by a factor of 3 in distance or a factor 9 in intensity (and we've included the pencil beam of the nearest gamma ray burst candidate in the calculations).

So, nope.
