Modernizr a part of WordPress?

I think that Modernizr is currently the best and highly useful library for detecting browser features. Something as useful as jQuery or Iris Colorpicker.

Shouldn't it become a part of WordPress? Many plugins and themes add it and developers need to use "function_exists" checks to prevent conflicts.

Having:

<script>
if ( Modernizr.touch ) {

}
</script>

instead of for instance:

<?php
if ( wp_is_mobile() ) {

}
?>

would be great!

And also in case of CSS styling I can think of many advantages:

.touch .element { display: none; }

jQuery and Iris Colorpicker are both used in core. Modernizr not.

If Modernizr should be used in core, then there should be a discussion first, which explains the benefits of using Modernizr instead of our current feature detection.
