I’m in favor of how this works at the moment. It was a bit jarring to me when the reproducible build flag was turned on and I lost all of the metadata that I subconsciously use during development. I think that what John has done is an appropriate compromise and is in line with how we’ve treated similar development-facilitating features in the past, i.e. WITNESS/INVARIANTS, malloc-debug.
