I think the SOP RBD Bullet solver is missing a group transfer/copy node inside the asset.It's a bug or something?

Currently groups do not get transferred like attributes do.
When adding the active age attribute and just activated groups, it was mostly to help with setting initial velocities for objects that have just become active, and help with other such effects.
If you need this just activated group outside of DOPs, could you submit an RFE for this? Optionally, we could change it to an integer point attribute instead of a group, which you could then transfer with the other attributes.
