 I'm the current maintainer, but I came late in the package life. Yes,
changing the quantum depth is just a switch for the configure script.
On the other hand, it changes at least two important aspect of the
programs using graphicsmagick.
The first one is the in-memory usage of graphics handling. It will
double the memory needed for the unpacked (ie, don't compare it with
the on-disk size of the image) pictures. Yes, newer architectures like
PPC64 will have several gigabytes of RAM to handle this. But on older
architectures like armel/armhf it may render the package itself and
related ones to useless because of memory issues.
The second one is can the dependent packages handle the changed
in-memory representation of the image? Who can test those in every
aspect at least on two architectures (little- and big-endian one)?
Fixes may be necessary for those and if their upstream is busy with
other things, the packages may be broken for a long time.
I can do a limited quick test on amd64, but the Release-Team will be
in position to allow this change or not.

Kind regards,
Laszlo/GCS
