Well, I do depend on image scaling, but I (like many others here, I
guess) build Emacs myself, so defaults don't matter much to me.

Question is: will disabling Imagemagick by default also have an impact
on how Emacs is shipped in distributions? I don't think so, at least as
long as they don't drop Imagemagick completely. If for instance Debian
has to take care of Imagemagick security issues anyway, why shouldn't
Emacs link to it?

But that's just my guess...
