The default position compression codec for point scattering should be 16-bit fixed point. This needs to be adjusted in points/PointScatter.h and the OpenVDB Scatter SOP.

I think it's important that the OpenVDB Points Convert SOP and the OpenVDB Scatter SOP have the same defaults. The Points Convert SOP currently defaults to 16-bit fixed point compression.

To be consistent, I wouldn't have a problem also exposing position compression as an additional option on the OpenVDB Scatter SOP that is only exposed when the output is set to VDB Points, provided that the default is changed.
