I agree. I have wanted to beef up the output of the launcher's "--help" for
a while now, but haven't had time. Since it is the "ImageJ launcher" I
think it should make a best effort to print out all of the command line
flags that ImageJ supports on the Java side, not just at the launcher level.
Of course, this may fall out of sync with what ImageJ supports, and in
ImageJ2 those command line arguments are fully extensible, so you might
turn on an update site that adds an option. We'll have to think a little
about how best to support that; I have some ideas.
I filed an issue for it:
