We may just disagree on what counts as significant for whatever reason, but I have had direct access to the resource management and capacity planning database of ADF-E and ADF-SW showing exactly how many of each geointelligence product was created and disseminated and for the RROC this included products being created from commercial sources. To me, they were not significant, but I understand this is not necessarily the case at a tactical level, for many of the reasons you're giving here like impracticality of downgrade to a classification level that actually allows you to disseminate to a forward-deployed commander only cleared for Secret.

For MDA specifically, though, we cracked that nut and can downgrade to the point we're just giving out pngs with no evidence of where they came from.
