Comment(by olly):

 I think the only sane way for this to work is for the multipliers to be
 real numbers in the range (0,1] - then you sum the wdfs multiplied by
 these and clamp to the nearest integer.  This could also perhaps help
 handle the "term occurs more than once" issue - count the occurrences up
 of each term front, then scale the scale factors for each occurrence of a
 term by 1/number_of_occurences_of_that_term.  Not an ideal solution
 though, I feel, but perhaps
 the best there is.

 Aside from facilitating that potential fix, I'm not clear what this is
 useful for ("it might be useful" seems the only justification), so I'm
 inclined to WONTFIX too, unless/until we have some compelling uses for
 this.

 I don't think this needs to block a merge anyhow.
