Comment (by joemcgill):

 `get_the_post_thumbnail()` is used extensively in places where the
 featured image is not in the viewport, i.e., on archive pages or in places
 where some UI is being creating using a secondary query, so we might want
 to be more explicit in that case that it only loads when `is_single()` and
 `is_main_query()` are both true.
