It gives me full control over the modules and not just appending to default set.

  #f --> default-kernel-modules (as it is now)
  '(some extraordinary special modules for other purpose) --> it will use this set
  '() --> it will use no module at all (my typical usecase)


But yes, it makes `extra-modules' useless.

I'd like to find a way, how to make default-kernel-modules available
as some lazy evaluated list (because what will go there is decided
when base-initrd is evaluated).

This is one of the steps for user defined kernel (besides specifying
kernel configuration) and I'm using it already.

If you're not against such change, it also would need to adjust
documentation (will do in next round).
