I might find that a good tool, too, but it’s worth pointing out that even doing that upon any change to the keychain trust settings won’t fix the full problem here. The bad “4” certs are also signed by another root, Sectigo, so when CRLs are not being used (a case that seems common for the cli tools), then the certs downstream of the “4” certs have an alternate path to a trusted root. Unless you also nuke the Sectigo cert. which I would personally, but I have a different risk tolerance for breaking random sites than I guess Apple expects its whole customer base to have in the aggregate.
