It's all part of the same discussion to me. I've filed
https://bugzilla.redhat.com/show_bug.cgi?id=2152229 now for the
original problem. Dropping the new deps of webkitgtk in lorax runtime-
cleanup is possible, but would be rather ugly and fragile (any time the
deps *changed*, we wouldn't necessarily notice and update the
stripping; we already don't update it enough and it's probably missing
stuff). It's much more robust if the unnecessary deps can be avoided at
source.

Still, that change in webkitgtk caused the images to grow by ~15M. The
lorax change I filed today saves ~11M and the iwlwifi change should
save ~30M I think. So no, actually, fixing the new webkitgtk deps
wouldn't make a "much bigger difference", though I'd still like for it
to happen!
