I have done quite a search before going into core code and besides
many people having questions there is not many solutions. There is one
soloution called "mini controllers" [http://www.noswad.me.uk/MiBlog/
MiniControllers] using components system (i have not examined it
indeep yet), but it seems too complicated for such a simple demand: to
have more layout elements.
I shall continue testing this hack. It doesn't seem to fail any of the
other view functions (e.g. caching, scaffolding), and on the end: it
is not that fundamental change afterall. Instead of view class calling
the final renderLayout method, this is done from within controller -
that's it.
