However, twin will NEVER be completely deleted. Why? I don't like relying on an upstream project (KDE) that has a history of seriously breaking things in new releases (history is history and cannot be changed). We need something to fall back on if kwin turns out to have serious problems (e.g. on certain graphics hardware), even if twin's codebase is never touched again.
This doesn't really make sense to me. KDE 4 development never broke the existing KDE 3.5 in any way. (It's also silly to say that the KDE developers prevented people from enjoying KDE 3.5 after KDE 4 was released.) If there would be a stable version of kwin4 working well with Trinity in the future, it will always be possible to stick with that version if newer versions would turn out to be problematic.
I see no problems in using an upstream project here at all.
