There were both glass scatter tests and specifications and impact tests/specs over the years, I don't think we can definitively say that the resin bonding was intended specifically to limit scattering, or only to meet the impact tests. If there is someone around who has access to the historical development of UL tests, or very unlikely, some manufacturer's documents (boy, would they not want that to be public), I think we can't say. The resin bond MAY have been mainly for dust exclusion, while the glass continued to provide the same protection as when it was air-spaced.

Can someone who has witnessed breaking a resin tube tell us if it captured all fragments like a windshield, or did glass pieces spray?

If the latter, then the resin may have reduced the force/distance of the spray, or may not. Actual test results with/without resin would be needed to answer this.
