What do you mean kde-workspace doesn't provide useful libraries? There are a
number of third party applications that depend on them.

Having a non-coinstallable kde-workspace 4.11 with the kf5 one means breaking
those applications, unless you keep an ABI compatible interface between
kde-workspace 4.11 and the kf5 one.

If you also plan to do an API change, it means to adapt those apps before they
are available for plasma2.

I wasn't part of the debian kde team when the migration from kde3 to kde4 took
place, but it's not a happy memory.

I think that this should be discussed in the packagers list, which will help to
sync our points of views among different distributions.

I can't predict the future, or how disruptive the change from kde 4 to kf5
will be for our users. As far as I could see, it shouldn't be, but the gnome
migration to gnome 3, the fallback support drop, etc, has brought new kde users
and some heartfillings about migrations, so making it as smooth as possible
will probably pay of.
