i'm for the second, i'm not tooo happy about exposing thumbnails in the
import
I'm against exposing the thumbnails at all. This has severe impact on KWin's
rendering performance. The taskbar thumbnail effect is designed for the usage
in the thumbnail were a few assumptions hold, mainly the fact that the window
is on top of all windows. Adding a plasmoid on the desktop rendering a
thumbnail could crawl kwin down completely.
So what's actually the use case of Thumbnails is Plasmoids? Remember a
thumbnail has to be of at least 200x200 pixels to be of use.

The use case exists. It's about the WorkFlow plasmoid in which I am
facing this issue:

Concerning the focus that the window effect is on top of all
the other windows, an assumption can be made that the plasmoid is going
to be used
as a popupapplet in a panel or in the dashboard. I also believe that in
the future
the tasks plasmoid is going to use QML. It may be too early for that
discussion but
until then the issue is going to exist.
For a start, I would be happy if I could take some screenshots(QPixmaps)
from
the kwin effect whenever the QML UI needs them. Instead of live preview,
tasks screenshots in every 500ms for example.
Cheers,
Michail
