according to Debian package information we have the following libraries which 
non-kde-workspace packages depend on:
* libkdecoration: useless as it requires KWin (Compiz case is no longer 
supported since 4.11)
* libkephal: got deleted yesterday
* libkscreensaver5: either already deleted or should be deleted
* libksignalplotter4: no idea what it is, if useful should go into a framework
* libkworkspace4abi2: no idea why external packages use it. The frameworks 5 
version doesn't look like it has anything of interest for external 
applications  - Debian name indicates that it's a bad idea to use it
* libprocessui4a: probably should go into a framework. It's strange that 
kdevelop depends on kde-workspace, isn't it ;-)
* libtaskmanager4abi3: the name of the library as adjusted by Debian should 
indicate why it's a bad idea to use it outside kde-workspace. Only used inside 
task applets, that should become a non-issue in Plasma 2
* libweather-ion6: same as taskmanager

There are a few more libraries, but all of them are either clearly "plasma" 
(libplasmaclock) or only used inside kde-workspace module

I can take it there, but only if packagers are willing to do the work ;-) I 
took it here to discuss whether we as the developers think that it is worth 
the effort to provide plasma 1 and 2 at the same time. I think we have 
agreement that co-installable plasma versions is not considered a valid use-
case by the developers. If distros think different, then we need help there.

That said: I would prefer that if at all the plasma 1 version gets adjusted. I 
don't want to type the rest of my life kwin5 and would prefer to still have it 
as kwin. So if co-installable the existing version should be called kwin4. 
Same for all the libraries.
