sitemap.xml generation incorrect date?

Bug description

When I use the command 'quarto publish' every post/page is recreated/updated in html, regardless of whether the page/content changed or not.

• Is this the correct/expected behavior?

using the above method, dates on the sitemap are not reflecting when the content was most changed

• how do you publish updates to some pages but not all pages (i.e. so the sitemap and dates are correct)?

another scenerio is you might change or remove a category on one page, quarto publish would regenerate every since post page and the sitemap. the underlying content technically didn't change on the pages, only meta-data displayed in one page

• why does this scenario record that the page/post content change for every page?

it seems that sitemap updated dates should relate to content, not navigation/meta-data ?

Thanks
