When importing variables allow size to be elided using '-' and then support a list of variables which restricts what will be picked during the import.

I'm pretty sure it's the same goal as this patch[1] I suggested.
It is, maybe it was your message I was thinking of when I asked the question the other day:
https://lists.denx.de/pipermail/u-boot/2018-March/323687.html
Could you answer in the thread telling you need it as well so that we could get it merged or at least reviewed?
Assuming I've understood your patch correctly, I think I can replicate your use case with this:
env import ... ${whitelisted_vars}
I've two uses for this right now for this - with different white lists:
# override defaults from uboot.env if fatload mmc ${mmcdev} ${loadaddr} uboot.env; then env import -c ${loadaddr} ${filesize} serial# ethaddr fi
# source OSTree deployments if load ${devtype} ${bootpart} ${loadaddr} /boot/loader/uEnv.txt; then env import -t ${loadaddr} ${filesize} kernel_image kernel_image2 bootargs bootargs2 fi
