I am indeed a bit hesitant to allow just a lisp form here, because erroneous setup of the remember template structure might then lead to hard-to-trace problems. However, I am fine with allowing a *function* in this element, as it is in fact already allowed for the target file name. I have just pushed a fix that will accept a function in this place and call it to get the true headline.
