I suspect that this would be more tedious(and potentially less flattering); but you'd think that the metric you'd really care about for the juche-computer would be component availability.
Going by cost is interesting if you are trying to get the attention of balance-of-trade types and tariffs and dumping hawks; but it's an almost perfectly wrong measure if you are trying to catch any "oops, turns out that only the Chinese vendors so hungry they are considering offshoring to Vietnam still make a random passive or unexciting tolerances switching IC because it's a zero-margin part with no real room for differentiation that everyone who could got out of years ago" type situations.
If it's a real, drop-dead, 'national security' problem some of those are probably less serious, if there's a much fancier TI part that is overkill for the job but could be subbed in for only 3-4 factors of ten more; but if you want to keep economically viable civilian production open or it doesn't have a direct upmarket analog that could get really awkward; even if you've ensured that all the fancy logic ICs, copper, and gold are geopolitically friendly.
That's basically the Nexperia story, slightly simplified. Philips decided to private equity semiconductors generally; NXP decided to shove a bunch of the boring parts out to WingTech; then 'oops' European manufacturers who need diodes and ESD protection parts they thought were cheap jellybean stuff have cars piling up on the line because they can't get them.
Obviously losing a really cutting edge capability isn't preferred; but it's also the sort of thing that people notice because those tend to be pretty valuable; while low and middling capabilities, including ones that are sophisticated enough that you can't just throw money at restoring them fast, are things that are voluntarily surrendered because getting rid of low margin products makes line go up.
