I understand.  Somehow, the output of Guix CLI is dynamic where Org
babel captures static text (the last output).  Therefore, maybe you
could demo using Gifs or something in this flavor.

Some special characters (as coloring) are from Guix and it should be
possible to turn them off.  However, others are from progress-bars;
some from Guix itselfs, other from guile-git.  Therefore, I am not
sure what you are asking, I mean, are you asking to be able to turn
off all the progress-bars?

Yes, my example was just... an example.  I am sure one could come with
more complex filters for formatting adequately.
