It is not a serious problem for me, because I don't expect that there
is any reason to believe that the sequence of numbers obtained by

  while true; do echo rand | octave -qf; done

should have any special properties.

The sequence of numbers obtained by running

  echo "rand (10000, 1)" | octave -qf

however, should be a pseudo-random sequence.

Then you should look at the code.  It is pretty simple.

If you disagree with the method of setting the initial seed, then you
are free to add some code to your startup files that will initialize
it in a way that suits you.
