Rabbi Yosef Kanefsky laid out some legitimate criticism of Rav Avi’s ordination of Sara Hurwitz, changing her title from Maharat to Rabba:

“Legitimate criticism would focus on the questions of timing and long-term strategies. Should the Maharat model been given significantly more time to develop before being surpassed? Might the ordination cause have ultimately been better served through twenty Maharats first establishing a track record of exemplary service to the Orthodox community over a span of 10 or 15 years? Does the move to full ordination right now compromise the ability of today’s Modern Orthodox community to solidly establish itself within the broader YU/OU/RCA community as an ideological force that cannot be dismissed or marginalized? Is the Modern Orthodox laity ready for this yet? These are legitimate and serious questions, forming the basis of potentially legitimate criticism.”
