Filter get_media_item output

[griffinjt]

L1027-1028 of media.php looks like this:

if ( $item = get_media_item( $id, array( 'errors' => isset($errors[$id]) ? $errors[$id] : null) ) )
			$output .= "\n<div id='media-item-$id' class='media-item child-of-$attachment->post_parent preloaded'><div class='progress hidden'><div class='bar'></div></div><div id='media-upload-error-$id' class='hidden'></div><div class='filename hidden'></div>$item\n</div>";

The biggest issue I see with this is that because you can only attach images to one post, this will unnecessarily display images that cannot be attached to the current post type in instances where the Media Library tab is forced to send items even though no editor support has been added for the post type.

In that light, it would be nice to have a filter to remove the output of these unnecessary items in order to improve UI and UX when navigating through images to attach to the post type. Currently I am having to create an error-like overlay on each item that is already attached in order to prevent users from trying to attach an item that is already attached elsewhere.

Where would it make the most sense to have this filter? At the end of get_media_item?

Hello griffinjt, sorry you never got a response.

get_media_item() is one of the functions which aren't used by core anymore, because of the Media overhaul in WordPress 3.5. Adding a filter here won't be much useful.
