AFAIK 4.02 doesn't do much more dead code elimination than 4.01. There is
an entry about dead code elimination in the changelog but it is a local
optimization that is unlikely to change the size of binaries much.

However there is a new feature of 4.02 that will help reduce the size of
binaries using Core: module aliases. Core will have to be updated to take
advantage of it. We are hopping to release a new version of Core using
module aliases soon.
