You are 100% correct.
It didn't fail me during testing because buildroot is never using any
compressed cpio archive, thus the previous options (gzip, bzip2) were
never used.
I noticed when checking the bzImage size in a tweaked qemu_x86_defconfig
test run that it never changed much.
New patchset will follow that fixes this and the previous issue.
Regards.
