With a some overdue compared to other BSDs, GNOME 3 desktop environment meta package was recently added to pkgsrc. Successful installations were reported by some NetBSD users including screenshots! Thus, I am also planning to give a try soon, since it is my default desktop environment in Linux systems. Currently, it can be build from sources only using latest pkgsrc branch. Likely, binary package will be available with the pkgsrc-2020Q4 release next year.
