You've got to realize that the commercial application of the parametric lists was always in the repair business.
If people aren't repairing their toys any more, manufacturers don't even publish service information, so the commercial justification disappears.
Get one US president or some pop-hyped billionair collecting semiconductors (or beanie babys for that matter) and you can bet there'd be a catalog along, shortly.
