If the layouts/manufacturing are still being finalized or put into practice, then it isn't really practical to switch to the newer technologies due to cost constraints. Besides which, newer technologies have their own problems that eventually come out; Just not visible at the onset. Researching and examining alternate possibilities is (I would say) a requirement of succeeding at development and innovation. However, investing too many resources into a technology before it has matured becomes a risky investment due to it's propensity for failure.
The reason most people use buck/boost topologies is due to:
Knowledge (not knowing of other solutions that would work)
Application (based on requirements, there may be considerations for why certain topologies are chosen)
History (They have been around for so long, there is very little difficulty in implementation)
Patent (often times the inventor of new technology imposes licensing/costs)
It is pretty easy to say: "Here are new technologies that will replace the buck/boost converters!" But actually going about replacing them is where the issues arise.
Although, I applaud your encouragement to Cypress to pursue the newer technologies and to constantly push the boundaries
