QML is a solution for a specific use case, it's not "the" future. QML also misses out on its widget set. It's too limited. There need to be a lot more widgets that work out of the box. Also excessive styling of elements seems to be needed. That's exactly something a developer can't do. Nice looking QWidgets were and are a simple way to empower a developer to create a useable UX quickly. Also there should be a C++-only API for creating Qt Quick widgets. It might be a good idea to leverage the c++ knowledge of your userbase, if your core userbase are c++ developers.
