AS7 was and will never be supported in 3.2. AS7 came along when the 3.3 cycle was already started. There's enough work already to provide you the best possible user experience in 3.3. We cannot spend even more energy to backport AS7 tooling to 3.2.
IMHO 3.3 is already pretty stable so that I'd strongly encourage you to do the switch :)
