As i understand things the benign aspect in Absalon is that the virus doesn't cause serious harm to that particular cultivar. If it spreads to other tulips it can however unfortunately still cause much trouble to them. Modern Rembrandt tulips are however as safe as any tulip as their pattern is created through breeding. They can however still become infected in cultivation and then the question is how does the color break manifest in an already broken tulip?
I did think that your precautions seemed sensible and should be enough to stop serious virus outbreaks, but that doesn't stop the gardener - in this case you, Mika - from worrying. I know that I would worry, so that is why I'm reluctant to grow them myself. On a couple of occasions I have however received broken tulips among "normal" cultivars, so one can never be really safe. However the good thing is that a color break at least most often is easy to see.
