Comment:

 Makes sense, thanks for clarifying!

 Unlike an empty comment, I don't think we can display an error for an
 empty excerpt, as that just means the excerpt will be dynamically
 generated by `wp_trim_excerpt()`.

 We can, however, use `trim()` before saving it in the database, so that an
 excerpt that only contains whitespace is saved as empty.
