We've long stopped discussing your project. The moment you suggested making
this a Qt feature, we stopped talking about your needs and we started talking
about everyone's needs. I expect you to come up with and consider a reasonable
set of use-cases when proposing Qt classes or a Qt module.

Yes, it might be a sad conclusion for your project, but it is probably a happy
conclusion overall.
QVector3D and the other math3d classes currently serve a purpose. Anything you
do to them requires that this purpose continue to be served. Moreover, the
source-compatibility requirement is in full effect. So you may propose changes,
provided that the requirements are still met, somehow.
You only proposed moving, with no plan going forward. I'd like to see such a
plan, how you plan on making changes (and when, considering that 5.0 should be
close now and that sets binary compatibility requirements). You have not done
that. So I simply cannot accept moving anything now and I think Gunnar feels
the same.
Instead, I recommend you start a new module doing mathematical stuff. In doing
that, you may need to address a lot more use-cases, like those Charles
mentioned in this thread. You might end up with something very close to Eigen
in that case.
