Actually, I fail to see where this approach _really_ reduces bandwidth

Users who are rebuilding the rpms, should learn to download the srpm
once. Afterwards, they'll have it "on disk" and don't have to
re-download it again.

I would expect the high rate of downloads of kernel-module-*src.rpms you
might be seeing at Livna to originate from delays between kernel
releases in FC and kernel-module releases at Livna.

Agreed. Also, it might not always be possible or not possible with
further effort, sometimes for technical reasons (Makefiles, build
infrastructure etc.), sometimes for licensing reasons ("Unmodified

Not for end users. They'd only see a kernel-module*.src.rpm and will not
know about the fact it had been split out elsewhere. But .. no matter if
the source are split into userland/kernel srpms they will have to
rebuild _one_ srpm.
