sticky posts - query.php optimization

[michelwppi]

Making improvements in plugin xili-language ​http://wordpress.org/extend/plugins/xili-language/, I use filter for get_option('sticky_posts')... and to find the right translation of sticky posts for each home language (demo shown here ​http://multilingual.wpmu.xilione.com/ ).
The call is at line 2473 of query.php. and done every time but only used if is_home is true.
To optimize I propose that this call of get_option can be encapsulated inside if condition as suggested below

if ($this->is_home) { 
get_option('sticky_posts');
if ( $page <= 1 && is_array($sticky_posts) && !empty($sticky_posts) && !$q['caller_get_posts'] ) { ///// 
}
}

It is microseconds for server but useful for hooking functions etc, etc...
