 Hi @henrykarl and welcome to trac!

 For user facing features, WordPress aims to design for the majority of
 websites with the guideline that
 [https://wordpress.org/about/philosophy/#:~:text=Clean%2C%20lean%2C%20and%20mean
 new features will be used by 80% of end users].

 While the majority of sites use a language pack other than US English,
 they're typically single language sites that don't have a use for
 `hreflang` tags so I think this is a feature that remains best in plugins.

 At its absolute simplest, I think a plugin could use a custom taxonomy and
 the `wp_head` action to output the header tag. Something like the
 following, untested, code:

 {{{#!php
 <?php
 function really_simple_hreflang() {
         if ( ! is_singular() ) {
                 return;
         }

         $permalink = get_permalink();
         $langs = wp_get_object_terms( get_post_id(), 'rsh_langs' );

         foreach( $langs as $lang ) {
                 $term_domain = get_term_meta( $lang->term_id,
 'rsh_domain', true );
                 $lang_permalink = preg_replace( '/:\/\/(.*)\//U',
 "://{$$term_domain}/", $permalink );
                 $esc_lang_permalink = esc_url( $lang_permalink );
                 echo "<link rel='alternate' hreflang='{$term->slug}'
 href='{$esc_lang_permalink}' />"
         }
 }

 add_action( 'wp_head', 'really_simple_hreflang' );
 }}}

 I've closed this ticket off as maybelater, which means that the feature
 can be reconsidered if the need for native support of the `hreflang` tags
 become more widely used in the future.
