It might actually be a worthwhile thing for distributions.

For a Fedora kernel, gzipping modules saves around 80MB of diskspace per
installed kernel.  That the RPM is compressed is irrelevant, the on-disk
footprint is more interesting, given that the bulk of the modules installed
will never even be loaded.
