Btw., even if we want to start simple with most things, the above
statement is not actually true in the broad sense: the constraint for
the kernel is utility, not complexity.
We have various kinds of highly complex code in the kernel and can
deal with it just fine. Throwing away useful ideas just because they
seem too complex at first sight is almost always wrong.
Thanks,
Ingo
