Good catch. I just looked it up and there are exceptions in various states for “holographic” (imminent death) wills handwritten without witnesses.

Actually, "holographic" has nothing to do with imminent death. It means "entire" + "writing" i.e. the will has to be entirely in the (identified) writing of the testator. Doesn't need to be made in contemplation of imminent death.

There IS some law regarding the admissibility of witness statements that are deemed a "dying declaration", in spite of the hearsay rule, but that's a different issue.
