i'd prefer also separate spec, monstrous specs with 200 lines of deps is 
definately hard to maintain.
and given linux-libc-headers.spec sample, it's also kernel dependant, 
yet we maintain it in separate package

and i'm sure people who want to maintain kernel don't want to maintain 
tools, which makes the tools packages low quality, no proper deps, etc
