USD Point Instancer Motion Blur

[doppelgaengerdigital]

I am instancing USD Data with an point_instancer in bifrost USD, driven by particles. It works veeery fast and I can render detailed geo on 800k particles with incredible speeds!
But what I found out, is that there is no motion blur rendered.
Looks like point velocity gets not passed to the renderer...
Is this supported in USD?

I reported this under issues, as other renderers seem to render just fine.
