A typical use case for what I mean, could be a discussion between
developers.  Probably about some internal issues or for explaining
aspects of the Topic Maps model for some example.  (Of course
this could be done using other notations, as well)

I can see that this is not the typical use of GTM level 0.
My  suggestion is just to keep the original notation as an option.

Do you feel the choice between several notations would be confusing?

I agree that your proposal is better suited for this, and for most work
on Topic Maps issues with clients.
