 @tsimonq2, Thanks, the following doesn't have an "experimental" branch: qtdatavis3d, qtnetworkauth, qtscxml, qtserialbus. Is that intended?
 @Santa, Yes, because they aren't released.
 @tsimonq2, But they have tarballs of them here: https://download.qt.io/official_releases/qt/5.11/5.11.1/submodules/
 Or you mean "not meant to be released in debian/ubuntu"?
 The packaging isn't fully complete for them yet.
 They also aren't in experimental yet.
