Thank you! My obvious bug was fixed in
https://dev.openwrt.org/changeset/44424/

Please note that if you still get
> Dedicated partitioner didn't split firmware partition, please fill a bug report!
with 44424, it means that there is something wrong in
target/linux/generic/files/drivers/mtd/mtdsplit/mtdsplit_uimage.c
and we/you should look for a working reference code in
405-mtd-old-firmware-uimage-splitter.patch
