How do I enable LTO in DUB in a sane way? I could add it to dflags, but I only want it on release builds.
You can put a "buildTypes" section in your package recipe and override default dflags or lflags there just for the "release" build type. See https://code.dlang.org/package-format?lang=json#build-types
