Save Site as Template: Why is the “include content” section available for some sites but not others?

Question

For some of our SharePoint sites and sub-sites, the "include content" checkbox is not available on the Save Site as Template page (in particular, Wiki sites). By "not available" I mean that the "include content" section is not visible, not just greyed out.

Why is this the case?

Answer 1

Here you have a list of what is included and what is not included when saving site as template:
