What is the status of jQuery’s multi-argument content syntax: deprecated, supported, documented?

Yes, it is from Stack Overflow: http://stackoverflow.com/questions/2932549/what-is-the-status-of-jquerys-multi-argument-content-syntax-deprecated-support




I've never seen this in any jQuery docs I've read; nor, have I ever seen it in the wild. I just observed multi-content syntax working here for the after modifier with jQuery 1.4.2. Is this supported syntax? Is it deprecated?

 

$(".section.warranty .warranty_checks :last").after(
  $
('<div class="little check" />').click( function () {
      alert
('hi')                                       
  
} )                                                   
  
, $('<span>OEM</span>')  /*Notice this (a second) argument */    
);                                      

Here is the signature for after: .after( content ). But, as my example shows it should be .after( content [, content...] )

I've never seen any indication in the jQuery grammar that any of the functions accept more than one argument (content) in such a fashion.

UPDATE: What did it do? I left this out thinking it was obvious:

It inserts a <div class="little check" /> with the aforementioned callback on .click() and follows it up with a totally new sibling element <span>OEM</span>.
