Comment (by joostdekeijzer):

 For those interested, a workaround below using javascript/jQuery

 {{{#!php
 <?php
 add_action( 'core_upgrade_preamble', function() {
   // !!! Currently WordPress does not support upgrade_notice for themes
   $themes = [];
   foreach ( get_theme_updates() as $stylesheet => $theme ) {
     if ( ! empty( $theme->update['upgrade_notice'] ) ) {
       $themes[ $stylesheet ] = wp_strip_all_tags(
 $theme->update['upgrade_notice'] );
     }
   }
   if ( ! empty( $themes ) ) {
     printf( '<script type="text/javascript">jQuery( function($) { $.each(
 %s, function( index, value ) { $( "#update-themes-table
 input[type=checkbox][value=" + index + "]" ).closest( "tr" ).find( "td
 .plugin-title p" ).append( "<br />" + value ); } ); } );</script>',
 json_encode( $themes, JSON_FORCE_OBJECT ) );
   }
 } );

 }}}
