Although they are both forms of explicit association, they're not 
included for the same reason.  These are some additional reasons for 
including for="" that do not apply to headers="".

* Allows for labels and controls to be separated, which allows for more 
flexibility in the structure and style of the page.
* Increased usability by allowing users to click on the label to focus 
the control. That's particularly important for checkboxes and radio buttons.
* It is very widely used in reality.

I disagree about it being logically inconsistent because of that rather 
significant difference, but regardless of that, it seems likely that the 
headers attribute will be added in due course.

Yes, whenever possible, that's a reasonable strategy to follow.
