vtk.js vs @kitware/vtk.js ?

It's been a little while since I've used vtk.js, in part because of the extra packaging required for loaders. I see that the new ES6 packaging under the @kitware namespace apparently fixes that problem.

Is @kitware/vtk.js the one true way of the future, and if so, are you planning to convert react-vtkjs-viewport over?
