Fit Canvas To Drawing from Command Line

As discussed in forum post here: http://www.inkscapeforum.com/viewtopic.php?f=5&t=4598&p=90664#p90664

I have a Ubuntu 14.04 LTS server running Inkscape 0.48 that is doing mass conversion from AI to SVG.
Part of the process is shrinking the Canvas to the size of the art work.
I've been able to successfully complete this using "inkscape --verb=FitCanvasToDrawing --verb=FileSave --verb=FileClose filename"
but this launches the GUI and slows down the process and is problematic for mass multi threaded conversions.

What is the best way to request the "FitCanvasToDrawing" feature be added as a command line only feature,
or is that problematic for some reason?

Thanks
