Project Settings missing Motion Estimation option

On the Edit page Inspector Panel under the "Retime and Scaling" section are settings for "Retime Process" and "Motion Estimation". The default value for these is "Project Settings".
Under project settings, down at the bottom of the "Master Settings" page, are the Frame Interpolation settings "Retime process" and "Motion estimation mode" which look to be the equivalents of the Inspector Panel settings described above.
But "Motion Estimation mode" in the project settings lacks the "Speed Warp" option that is present in the Inspector Panel. Is that intentional? I'm wondering whether to report it as a bug or not...
I have the Studio version of DVR, so it's not obvious to me why that option wouldn't be available as a project default.
