I wonder whether than means hardware graphics acceleration will
become a requirement to use Qt5 based apps. The GNOME developers
traveled that same road with GNOME 3.
Apparently it will:

But OTOH GLSL is a high-level language, and llvmpipe enables
compilation from shaders to optimised x86, so doing the rendering with
OpenGL ES shaders rather than custom C++ is not necessarily a big
performance loss even without hardware 3D acceleration (we'll have for
example the advantage that LLVM will target the exact available CPU
features).
GNOME 3 mandatory compositing/OpenGL reportedly already works without
using hardware GPU acceleration:

Obviously we'll have to see how it actually works with Qt5.
