Another more common examples:

* in meta-qt5-extra I could fix many recipes by depending on
qtbase-native although they already depended on qtbase (qtbase depends
on qtbase-native)
* right after recipe specific sysroot a dependency on qtbase-native
was added in cmake_qt5.bbclass although it depended on qtbase already
and qtbase depends on qtbase-native

Before we carry on adding dozens of dependencies and blacklisting
world: Are missing native dependencies a bug or a feature - or where
am I going wrong? What scares me most is that my way of depending
always on cross recipes in meta-qt5-extra will not work anymore
(mentioned in my previous mail) and turn into a unmaintainable burden.
