AFAIK, kit vendors made manual degassing mainstream in their effort to reduce the time to bottling by speeding clearing. I'm sure the technique was in use long before then (25+ years ago?), but kit vendors pushed it and made it a normal part of their process. After all, it works.
One concern is the use of the term "whipping". When manually degassing, I'm not trying to introduce O2, nor is that a good idea. O2 is necessary during fermentation, but once that's done, O2 is the enemy. I get a small vortex going, which initially emits a lot of CO2.
A good experiment would be to create 3 identical batches, especially if all fermented together. #1 is degassed for 3 minutes, #2 is degassed for 1 minute, and #3 is not degassed at all. Check at the 3, 6, and 9 month mark for differences, and periodically after bottling.
