On https://lists.w3.org/Archives/Public/www-style/2015May/0285.html
was discussed about the necessity to gather data about it. 

Firefox is currently the only one to NOT implement zoom [1], and it creates Web Compatibility issues for at least two sites in Japan.

* Tokyo Metro
  https://webcompat.com/issues/1118

    if (userAgentCheck('iPhone', 'iPod', 'Android')) {
        $(window).bind('resize load', function() {
            $("html").css("zoom", $(window).width() / 640);
        });
    }

* CircleSunkus
  https://webcompat.com/issues/952

    <html style="zoom: 0.5625;">

and

    //viewport
    $(window).bind('resize load', function
    (){
        $("html").css("zoom" , $(window).width()/640);
    });

This is not much, but at least some concrete data. 
Mike Taylor has also written [2] about it.
