Rebuilding the kernel tens (or hundreds) of times may be rare for most
ordinary users, but it's quite common for kernel developers.
Rebuilding the entire kernel every time you make a small change is a
big problem and cost a lot of people a lot of time - and the people
who will bear the cost are the ones who have to build many kernels.
IMHO this is a big problem.
