If that's true (and it sounds good to me) then one might interpret
the advice as "don't nest for the sake of nesting; nest only to
manage complexity".
It is not necessary to nest to manage three items. It might be
necessary to nest a little more to manage twenty or thirty.
Several hundred or thousand need a little more (i.e. the standard
library, which does have a few levels of nesting, such as package
xml).
