At a first glance I thought that --gscmd was supposed to replace
options too, but obviously its purpose is to change only the program
name.  It's probably superfluous since $^O is checked already.

Yes, this can't work.

Sounds good, but it should be ignored if ($restricted != 0).

IMO the benefit is very small because you can't pass arbitrary options
to gs this way.  The order matters.  I suppose that you can write

  gs -dNOSAFER file1.ps -dSAFER file2.ps
