I don't know, but the risk profile seems to be expanding significantly as the number of parts increases. Micron at least scoped it to specific lines, and form/functional substitutions.
Here I see the production equipment (fab, test, encapsulation) can't be sustained endlessly, as replacement parts, costs, stock market and geo-politics are factors, let alone third-party risk for outsourced packaging, or unique technology.
What I'd perhaps prefer to see is some better/stronger guidance on designing for longevity, and perhaps that you might have to refresh the design over the life of a product to accommodate changes in part availability and pricing structures. For examples connectors may fall out of favour as a vendor using millions of the ones you've picked migrate to different ones, and the economies of scale change.
