She's not Unlisted, just not Open, and legitimately so under the 100/150 year rule.
But if I understand your point, I agree with it. It is unreasonably and unnecessarily difficult to find a dead person's non-Open profile from the profile of a connected relative. There is no good reason to hide the name and profile link on the relative's profile, when it's visible on the person's profile. If only you can find said profile.
