My stance is that the problem is minor (I cannot even see it on my
system, so it could well be specific to NS), and thus the change is
unjustified because its benefits are basically nil.

If that same change would motivate a redesign I described, we'd
benefit much more from that, so it would be justified to sustain even
greater risks.
