It handles the case when you have modules that don't get rebuilt as part of
the base kernel. It allows you to build fixed kernel images without spending
ages rebuilding all the modules when they otherwise match

Unrelated IMHO

Which occupies almost no space

The kernel release isnt useful info. Many interfaces are stable across
multiple kernels, many interface issues depend on things other than kernel
version. Lots of people apply patches and don't change the base kernel
version - in fact its hard to do so

I think so. It solves the first 95% of the problem. Solving 100% isnt easy
enough to be worth it. Throwing it out and solving 0% of the problem is
not very bright either
