The sitemaps need to be valid xml, but they should also be links that matter.
Some agencies might simply point to the press release section? Others may be every page of the site. Sometimes there are multiple sitemaps for different purposes. Sometimes these are described in the robots.txt file, but generally they aren't well defined.
I don't know how you tell good vs bad sitemap.xml files. Possibly correlating the age of the files. If the files haven't been updated in more than a year, likely it's not a very useful list of URLs.
Describe the solution you'd like
I'd like to see a count for the number of URLs.
I think there's space to look at date, or format. Is this a custom built list of URLs or is it something that is obviously just spit out from the Drupal Sitemap.xml module?
Additional context
On a different note. Rather than bold might be better to make these all headings:
Is your feature request related to a problem? Please describe.

https://www.cms.gov/sitemap.xml has 55 pages of URLs. That's a lot.
The whitehouse has them broken down into a number of categories: https://www.whitehouse.gov/sitemap_index.xml
Only 2 are highlighted here, and they are not documented: https://www.whitehouse.gov/robots.txt
Here's another example where they have the content broken up: https://www.loc.gov/sitemap.xml
Which one would you choose to start with?

Heading 2
Is just easier to navigate than a bold.
