That is plain wrong.

Even under the worst conditions objects of size 0.001 will still be rendered
correctly.  As will objects of one million units in size and offset.  Beyond
that, it depends on many details, but it can in general be assumed that
values beyond 10e10 and 10e-10 respectively will never produce correct
results.

I have scene that had problems on 3.6, I will try to post minimal source to
