I think it would make sense to have at least optionally the legacy code=
 (QWidget + X11)=20
without an OpenGL ES requirement. For QML2 and QWidget on Wayland the G=
LES=20
requirement makes sense.

It's not only leaving quite some hardware behind, it's also that I doub=
t that the free driver=20
stack will be anywhere close to the maturity required for all applicati=
ons using OpenGL. If I=20
consider the trouble we have with just one application defaulting to Op=
enGL...
