Not everybody uses (or should be required to use) a KDE video player in order to make their system work in a reasonable way. I only occasionally watch videos, normally in a browser, and I don't see why I should have to find out how to create and use a special activity (I don't use activities at all so far) just because I can't manually select the presentation profile any more. I want to just click on a link in the browser I already have running, and select presentation mode, not restart the browser in another activity to view the video. Or perhaps I have misunderstood your proposal?
