What problem do you see this solving?
The ability to edit RAW with a section outside the image with a repair mask/clone mask would be very desirable.This is possible with panoramas
When was the last time you were affected by this lack of functionality, or specific tool?
Regularly
Are you using any workarounds or other solutions to achieve your goals in Capture One?
Edit the image with cutout as TIF in GIMP and unedited back in CO, then edit the repair mask/clone mask in CO.
