Antimony: exploring alternative build systems

What is missing for me at the moment is a way to recover the individual swift-frontend invocations as one was able to do from the .xcactivity logs until Xcode 16.3. Could a there be a build setting to opt into the legacy logging behaviour? I use this in the InjectionIII project as I believe build systems are struggling to scale and the focus should be on incremental builds, ideally injected directly into the running program using a dynamic library. I need to be able to re-compile individual swift files as quickly as possible.
