I started playing with the Underscores starter theme and noticed it uses
esc_html_e() even on plain text:
<a class="skip-link" href="#content"><?php esc_html_e( 'Skip to content', '_s' ); ?></a>
Is it any security risk not to escape it like so:
<a class="skip-link" href="#content">Skip to content</a>
... or is it there just for the sake of translation?
