This functionality has been implemented for the Special namespace, in r93758. See bug 15558. I am proposing extending this support to all namespaces.

The main use case on my mind to friendly-ize auto summary messages like the Undo summary. Currently, the message reads "Undo revision 318 by...", where the revision oldid is not a link. In this case, it would be really convenient to provide an "Articletitle?diff=318&oldid=301" sort of thing, but it seems to be impossible with the basic msg->text() expansion. Similarly, there are cases when it would be useful to link to something like "Article?action=protect", in contexts where full parsing is not performed.
