We tend to assume that the AA pipeline is by default the default AA pipeline and it's confusing when it's empty instead. PR48779 Initially reverted due to BasicAA running analyses in an unspecified order (multiple function calls as parameters), fixed by fetching analyses before the call to construct BasicAA.
