SS Pro is not the same as SSE, as we all (mostly) know. If I understand right, the engine for SSP is actually based on SS9, and SSE is a NEW engine... - a guinea pig experiment, possibly.
Anyway, as Capt D says, it is ir-relevant. However, even if it is in seperate environments, if they are faster loading and do not stop the ship whilst loading (think how MSFS does/did it) then perhaps that is viable.
