We'll see in a few days if migration to testing is that simple :p

That's good news.  I've noticed while packaging xtensor and dolfinx that 
even arches that pass xsimd tests (including amd64) still fail using 
xsimd data structures in other applications.  Good if upstream is 
actively working on improving support.
