I am saying that there are enough libraries or plugins depending on QtQml or 
QtQuick, causing a lot of Git repositories to depend on qtdeclarative. That 
puts them in the critical path.

On a switch to a different buildsystem, if it can determine that things like 
qttools/src/designer don't depend on QtQml, it can start building that 
earlier, which should increase parallelism.
