--- Comment #1 from Kunal Mehta (Legoktm) legoktm.wikipedia@gmail.com --- I think so too, but I'm not sure if 'expandtemplates' is the clearest term to use for this. Maybe 'includetranscluded'?
In any case, there should be some documentation on the parameter added. Could you do that? Thanks!
(unfortunately there is no option for 'accepted, but waiting for updated patch...')
