Why not let them create their own deliverables?
Because then it's not a deliverable. The whole idea of a deliverable tends to be to deliver the project in the final format needed to make distribution copies, color-corrected, etc. Now for archive reasons, a feature distributor may want all picture elements including R3D files, etc. just as a TV broadcaster may want a 1080P 4:4:4 Log master as well as the 4:2:2 Rec.709 master.
But to deliver R3D files to them and tell them to finish it themselves is basically not delivering a finished project. Plus it may not be color-corrected to the look you want.
