@michael-basil , you asked if SAP could be included as known instance, you may want to review this PR.

I recommend to squash this when merging, as I had to send a commit to fix a linter finding.

Thanks for this PR @dellagustin-sap. Left a suggestion inline.

Btw, is the CPA that you describe in the blog post similar to an industry body that consists of representatives of different companies to define a standard for the greater benefit of everybody involved? Wondering if the CPA is a similar idea but implemented within a single org.
