Having done lots of both QML and QWidgets there are many tasks for which I feel I'm more productive on the latter. There are also regular posts on the Qt mailing list asking for a complete c++ version of Qt Quick, and people who kinda implemented a similar thing in another library (QSkinny iirc?)
Like, in c++, I just type approximately what I want, especially when writing glue code or creating a new api, and add compile-time checks & fix compiler errors until things build which is a super fast process ; with QML (or other less strict languages) it takes much more time in a slower edit-run cycle to write correct code.
And this is mainly due to new c++ features: what would have taken fifty lines to define a static check for in c++03, 30 in c++11/14 with e.g. enable_if, takes at most a couple in c++20 with concepts
