Change release schedule 4.2 and schedule for 4.3

When I first hear about the changes, I thought/understood that the new
architecture was almost decided, it was something like:

- Qt-copy, Kdelibs and probably (to be decided) kdebase in SVN , 6 months
release, nothing really changes there. (i.e. stations, not only summer)

- In SVN there will also live files with links to external repositories and
their status (may be GIT repositories, but to be decided). Status would be
an ORDERED list like development, feature freeze, strings freeze, docs
freeze, ...

- Some external (gitorous?) mechanism to let easy navigation, forking and
branching of external repositories (aiming at casual contributors?)

KDE will continue to have 6 months releases with the same phases (feature
freeze, etc.) that applies directly to everything on SVN and apply to select
the correct repository to pull the code from.
To make it clear. Let's have Kopete with a 4.2 code branch or repository and
a 4.3 repository. When feature freeze comes, if the repository for 4.3 is
not marked as feature freeze status or superior, then the 4.2 branch will be
It means that any project can skip a KDE release if it is not able to be
ready on time or simply don't want to be tied to the same 6 month release
than the rest of KDE for whatever reason (Plasma?). Obviously most projects
want to release often so won't skip KDE releases.
It also means that kdelibs is the base with a known schedule and status.
Projects can release independent from KDE. Each KDE release will fetch the
last stable version of each project (much like Xorg does).
Scripts will automatically pull all the relevant outside branches, fetch the
code and build all KDE.

I was sure it was the idea someone proposed before and more or less
accepted. But reading this thread, it seems that the new development model
is far from decided. Is the "always summer in trunk" already decided?
