zAAP's are indeed used by Java code running on a TCB. However, to my knowledge, it does not follow that: "With zAAP on zIIP, they must be using SRB's." IBM determines the rules in this regard.
To me (as both an ISV and System z developer), IBM allowing more code to run on specialty engines is a VERY good thing. It continues the controlled reduction in the cost of System z ownership. As a side benefit, it has also promoted innovation within the ISV community. For example, by zIIP enabling our integration products, some of our customers were able to deploy very cost effective solutions that would not have been possible otherwise. This has allowed them to expand their System z workload. I don't think customers mind using (and paying for) high-value MIPS for high-value apps. However, everything else (e.g., integration and "plumbing") should be run on specialty engines (within the bounds of IBM's rules).
