Quick addition, APAS fell out of favor in Russian circles simply because of mass. APAS is of a much greater mass than SSVP leading to the situation where only 2 cosmonauts could be flown instead of the usual 3. The mass of APAS attached led to too many sacrifices elsewhere on payload, so SSVP was carried on.
The only time APAS-Soyuz actually flew and docked with another spacecraft was Soyuz 19 (to Apollo) in 1975. The last Soyuz to fly with APAS (75) was Soyuz 22 in 1976.
Where APAS was ok was when it was part of the Buran space shuttle program and the Mir-Shuttle programs (APAS-89). Later APAS-95 was no longer androgynous.
