So are we saying the variable editor feature is the solution and there will never be a reason to show more than 10 elements of an array in the "Value" column of the "Workspace" panel table?

If so then let's just call this won't fix and refer to patch #8656 as the solution.

If you are able to build Octave yourself, you can try the Variable Editor from patch #8656. That will allow you to view as large a matrix as you wish (within screen limits) and even allows editing values and copy/paste to/from other programs.
Although not quite feature complete, and the usual warnings apply, I find it very useful and I often invoke it.

I just uploaded a cset I have made a while ago from the patches in that patch report and that still applies to dev Octave.
Just do not try to use the "autofit" option in its prefs, it'll unacceptably slow down painting the variable editor pane.

Consider the following code:

mat=[ 1,2,3; 4,5,6; 7,8,9; 10,11,12 ];

If you set a breakpoint at the second line and run the script, you'll see the value of `mat` in Workspace view as

mat double 4x3 [ 1, 2, 3; 4, 5, 6; 7, 8, 9; 10

This is hardly usable for 4x3 or larger matrices. One has to explicitly use `disp` to show such values, and Workspace view becomes useless.
This looks especially miserable on hi-res screens like 3840x2160.

I'd suppose the view should print as many elements of matrices as it can fit in its width. Or at least have a user-configurable limit for displayed element count.
