This tells me that mozjpeg installs files over the top of the jpeg
package and, in order to install it, needs to remove everything that
depends on it.

pkg has no way of knowing if mozjpeg has the same API as jpeg,

I really have issues with the default behavior of deleting all dependent
packages like this without an obvious way to deal with it.

I suspect the official way is to is to use a set -o old-pkg:new-pkg:
pkg delete -f jpeg (-f prevents all dependent packages from being deleted)
pkg install graphics/mozjpeg
pkg set -o graphics/jpeg graphics/mozjpeg

Odly, I note that graphics/jpeg is a dependency of graphics/mozjpeg, so
color me a bit confused. I also don't understand why gcc and gcj are
dependencies. I guess mozjpeg requires the run-time libraries.

And why has Firefox decided to switch my language to UK English??? Weird
morning!
