savings and potential improvement in throughput are staggering in some cases.

In our architecture, non-SRB safe activities are serviced by a TCB.
CICS-specific activities are of course serviced by a CICS TCB.

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 i
. If fact, there's an
option to not even run it under an Enclave SRB. This approach holds true for
the following products: HB Base, HB JavaScript Engine, HB Socket Support. HB
BPIC (Batch Programs Inside CICS) doesn't exploit zIIP.

we compared the cost of: (a) frequently starting Enclave SRBs, and (b)
using a "persistent" Enclave SRB in conjunction with MVS Suspend/Resume
services. We actually ended up using both techniques in our product
(although in different situations).
