Responding to a question regarding Munírih Khánum, I would note, as I've already quoted, Ruth White on Abdul-Baha's "family, with the exception of his wife and sister...."
"In fact his family, and "in-laws," with the exception of his wife and sister, were somewhat materialistic, and viewed the religion more or less as a little family affair with a strong bent toward organization."
"...partly nullified the great universal teachings."

"Ahanu" seems to have a predilection for putting words in other people's mouths and then turning them to his own purposes. I would stick with the words of Ruth White. The burden of proof regarding whether or not the purported will and testament is authentic rests with the Haifan Baha'i denomination.
The overwhelming evidence as discussed in the "Website Suggestion" thread, citing,
Dr. C. (Charles) Ainsworth Mitchell's Report on the Writing Shown on the Photographs of the Alleged Will of Abdul-Baha. 1930. Certified Copy from the Library of Congress.
Dr. C. Ainsworth Mitchell, Report on the Writing Shown on the Photographs of the Alleged Will of Abdu'l-Baha
and citing,
Ruth White
Ruth White
clearly demonstrates substantial "prima facie" reasons for further investigation of the authenticity of the questionable document, especially since both Shoghi Effendi and the family of Abdul-Baha benefited monetarily from it but refused and denied all efforts to determine its reliability.
Since 1921, throughout the decades, significant reasons have only continued to mount to call the "will and testament" into question.
