I totally agree with all you said. I don't like having a separate 
argument just for being able to set a return page. Furthermore in some 
situations you need more than a pid. You maybe need an action or another 
controller or some custom arguments.

There are two ways I can think of:

* Store the history in the session object (like history object in JS)
* Determine the "backPid" based on conditions of current settings.

Generally those two solutions are those mentioned by Christian already.

And if you really need a custom URL, you can always use the "arguments"
array in the link view helper to set a customized URL (urlencoded) and 
use it later on in an action to redirect back or render a back link.

JS is imo no solution, just a gimmick (buzzword "unobtrusive JS").
