Thread:Talk:Requests for comment/API Future/"agent" parameter

It seems to me that this is redundant to the HTTP User-Agent in all cases except XMLHttpRequest-based clients, and to be useful for most cases it would have to be required to be in $_GET (so it would show up in the webserver access logs) even when the rest of the request is posted.

In other words, I'm not sure that making it required for all clients is really a good idea.
