The repository for the Standard for Public Code is made as neutral as possible - it contains only the standard, with all the stewardship related things moved into About. I remember this was to make the Standard a stand alone asset anyone can use and reuse as they see fit, while stewardship is something particular to our organization.
However, I get the sense this separation is not made as clearly on the homepage. The introduction to the standard page includes a lot of "how do we do stewardship" information that perhaps lives best on the introduction to stewardship page.
If we want to promote it as an asset separate from our stewardship activity, it would be best to untangle these two elements, keep the standard page strictly about the standard (and include community-inviting things like the community calls, translations, different ways it's being used and by who, etc) with a mention+hyperlink that we use it for stewardship. And then move all the audit/certification content to the stewardship page.
