Shellac was a fair bit better than Minnesota Mining and Manufacturing's Fast Tack, and even more so than Mastic type glues. In my opinion, this most likely had to do with the fact that Mastic glues allow the tire to "squirm" a bit on the rim, deforming not just on the sidewall, but across the whole carcass's cross section at the contact patch. 3M Fast Tack is more rigid (because you need less of it, so not as thick), and Shellac won't move at all where it's adhered.
While that is true, keep in mind the age of those tests and the glue available at the time.

Many pro/world record/etc tires have been epoxied in the past as well for the reasons you mention, although again, some of that data has some age at this point.
