That's a hard question to answer and that's a shame we have to, not
releasing an API that goes against 20 years of Qt history would have been
I don't think QML versioning would help. Having completely different
function signatures between `import QtQuick x` versus `import QtQuick y`
would be super error prone.
Maybe a compile time flag? a runtime one? To switch between the current way
it is done and a saner and consistent with the rest of Qt one.
