The \Drupal\taxonomy\Entity\Vocabulary plugin's ::view() function has an alter hook...
// @todo Test & Document
// Add an alter hook for modules to manipulate the taxonomy term output.
$this->moduleHandler->alter([
'sitemap_vocabulary', 'sitemap_vocabulary_' . $vid,
], $list, $vid);
This defines a hook_sitemap_vocabulary_alter() and hook_sitemap_vocabulary_VID_alter() public API.
But as the comment says, we don't have a sitemap.api.php file to document that, and we don't have any tests.
Document the alter hooks in a sitemap.api.php file and add tests.
None.
Documents something that's already part of the public API. This increases its visibility, but isn't an API break.
None.
