I have no doubt about all this. I suppose there is an in-developement 
process about how to handle
this situation the development team. Maybe it will be a deprecated 
function in the future.
Either way, by the discussion here I suppose that there are two trends. 
One that the window
thumbnails should be available only in kwin and one that they should be 
available also in plasmoids.
This is a question about how the tasks plasmoids will be implemented in 
the future. I cannot
provide any opinion around this dilemma, the development team is going 
to decide.
Until then I will wait for the official implementation of tasks 
plasmoid. In a month I will upload
a video showing my current use case and from so far I havent noticed any 
drawbacks with
Plasma::WindowEffects::showWindowThumbnails. I dont know what are the 
issues but I havent
noticed any in my implementation so far...

Cheers,
Michail
