Most notably, it contains a discussion about the feasibility of a fork (and even a name is discussed). What emerges from the discussion is that the OSS community around the Qt project is quite large even outside of KDE (I remember VLC being cited, for example), and that if efforts are united, it would be feasible. The KDE project could provide the necessary infrastructure for development, including CI (which would necessitate some startup work to change framework if I understood correctly) and distribution.
According to one coverage report the project sizes are 7 million lines for Qt vs. 1.2 million for GTK. If true, they are indeed much closer in size than I imagined -- I was sure it's at least one magnitude of difference in size if not even much more.
