I had omitted the Display-If-Visible header (which has been discussed since 2007 at least) deliberately, because we want to get format 2.0 done in a timely manner. The problem with any visibility filtering is that visibility depends on user configuration [1], and I don't know what changes in the package manager would be necessary to make this work correctly and efficiently. For example, how does portage's --autounmask-write option interact with it? Ulrich [1] https://bugs.gentoo.org/show_bug.cgi?id=290038#c9
