Well that kind of didn't address my comment lol. Although I do agree about the freezing bud becoming brittle, I believe that has a negligible effect. During long term storage the jars wouldn't be moved nor would the bud be agitated much. Even if the trichomes do fall off of the bud, they will be caught at the bottom of the jar. Also, what is on the outside of the bud is a fraction of the total THC that bud contains, so even then you will still get high if you smoke it.
So back to what I originally wanted to know is if vacuum sealing during curing impacts the process?
