I thought directwrite support was dropped because it was too unstable. I could
be wrong though.
No, I think the difference here is that Qt Quick 2 used depth maps to render
glyphs, which allowed for smooth scaling. In most cases, the new font engine
would produce much better results than other engines. However, the results are
still *different* and on Windows they're different enough that people started
asking for the ability to render text using GDI again. That's the feature.
