Sure…makes no difference for use with TR. But Rouvy found a way to use Zwift’s electronic shifting tech in their platform (and without using the Zwift Cog, although you technically don’t need it for use in Zwift, either). SO if you are riding in Rouvy and need to shift as the terrain changes, you can just use electronic shifting now.
It does add more gear range than some real-world drivetrain systems, so that is a benefit (especially since my trainer bike is a Campag 9 spd system w/ a 53/39 crank and 25t lowest cog 
)
How the hell I ever rode that gearing when I lived in CO is beyond me.
