Beningnuman,
If you would be up to date on the Matzav in Eretz Yisroel you would be aware that essentially was the crux of the huge machlokes regarding Geirim.
Rav Elyashiv made it clear, very clear that in his opinion many of the converts that went through the process of Rabbi Druckmans system were not Jewish and yes, that was the position of Rabbi Avrohom Sherman who is Dati Leumi and was the “Whistleblower” in many cases.
