Given that we are now no longer recommending ImageMagick, perhaps
GraphicsMagick support feels more relevant now than it used to?

From my point of view, GraphicsMagick has better performance, half as
many dependencies, and way fewer CVE's.  Like ImageMagick, it also gives
us "free" support for a ton of different image formats, and "free" new
ones in the future.

On the flip-side, I personally get by just fine with our built-in
support for JPEG, GIF, SVG, PNG and some others (this list will include
WEBP in Emacs 29.1).  So I have no idea what need our users have for
support for a wider range of image formats.

One final consideration is that GraphicsMagick support could be a step
towards making our ImageMagick support obsolete.
