kde-plasma/plasma-integration-5.6.5 have a hard dependency on media-fonts/noto. I don't see any reasons for this. Noto fonts is a huge package, 16MiB, and I don't even use it. Yes, it may sound a bit selfish, but I want to know reasons for such dependency. Reproducible: Always Expected Results: USE flag for media-fonts/noto.
According to upstream: plasma-integration uses Noto Sans (https://www.google.com/get/noto/) and Oxygen Mono (http://download.kde.org/stable/plasma/5.4.0/oxygen-fonts-5.4.0.tar.xz) fonts, ensure these are installed for use at runtime.
Required by upstream.
