Comment (by swissspidy):

 With similar template tags I meant `get_permalink()`, `get_the_title()`
 and basically any `get_` function. They all allow passing a `$post` while
 their `the_` equivalents display the values for the current post. In theme
 templates, `the_excerpt()` is usually used, whereas `get_the_excerpt(
 $post )` can also be used by plugins — without manually needing to apply
 filters.

 > Isn't it an option to put functions like this in WP_Post? and change the
 theme functions to call the methods in WP_Post. As a plugin developer I
 would love to use WP_Post more and doing something like this would be a
 good step.

 Oh, I think it is. I haven't found an existing ticket for that, but I've
 seen plenty of code examples of custom `Post` decorator classes
 implementing something similar.
