The rings QQbar and AA are awesome for a lot of reasons, but they
don't have a singular counterpart. So it means that all the
functionality of polynomials over those rings, that relies on
singular, is broken. We can't compute resultants, discriminants,
primary decomposition and so on. We just have a toy buchberger
implementation for groebner basis (which is great to have, by the
way).

Do you think it would be worth implementing all these features
ourselves? Is there some movement in the Singular community to
implement these rings?
