Could we avoid (some of) this by treating “source” as a new architecture? There would be a mostly do-nothing buildd which would repack the source package as a binary package in /usr/src/... That would still mean we’d have to add meaningful arch-qualified build-dependencies in all the affected tools, and it doesn’t help with the transitive dependencies (although the binary package containing the source could carry the appropriate dependencies), so perhaps it’s not such a great idea.
