is_ajax()

I noticed in documentation that 

PHP Code:

$this->input->is_cli_request() 


is aliased with 

PHP Code:

is_cli()  


function of Common.php file.
There is said first one is now deprecated and seems it will be removed from framework.
I just wondered is there idea/plan to do that with 

PHP Code:

$this->input->is_ajax_request() 


too.
