Being in the financial services business, I'm with you on this. Any program change requires full regression testing, including "just a recompile". We do not recompile at all once changed source code is tested by the developer and moved into QA. All moves into QA and into Prod are just IEBCOPY operations. Code is tested and quality assured as-is from the developer.
It is the developer's responsibility to make sure nothing broke and that new function operates as specified. ABO does not change that mandate, so it had better have been done before the developer performs the required testing and certifies a change as "ready for QA". The potential impact of an un-caught bug or even just an unexpected change in business process behavior on the reputation and client base of a company is immense and cannot be ignored (especially in this social-media-frenzied environment), and I would venture to say that any any business type you care to name has that same risk.

While I believe that ABO can very much help old COBOL modules (and even those sites that don't have corresponding source code), it is a change. Your industry may have different compliance requirements. From a performance analyst perspective, I'd have much interest in the before and after effect of implanting ABO.
