I suppose using --label would be ok, though I don't really like to
overload things like this in general, and it forces the partitions to
have labels.

The listing is supposed to tell the user where it found the artifacts as
a sanity check, e.g. what the variables or -e expanded to and thus where
the artifacts came from. /var/tmp/wic/build/hdd/boot doesn't tell you
that.

That seems kind of unreadable to me. Why not just add another
ROOTFS_DIR line for anything beyond the default rootfs e.g.
ROOTFS_DIR: /home/trz/yocto/master-cur/build/tmp/work/crownbay-poky-linux/core-image-minimal/1.0-r0/rootfs
ROOTFS_DIR["secondary"]: /home/trz/yocto/master-cur/build/tmp/work/crownbay-poky-linux/core-image-minimal-dev/1.0-r0/rootfs
BOOTIMG_DIR: /home/trz/yocto/master-cur/build/tmp/sysroots/crownbay/usr/share
KERNEL_DIR: /home/trz/yocto/master-cur/build/tmp/sysroots/crownbay/usr/src/kernel
NATIVE_SYSROOT: /home/trz/yocto/master-cur/build/tmp/sysroots/x86_64-linux
