You are missing 2 things:
1) TIP #717 is for Tcl 9.1, _not_ for 9.0.2. It's not a good idea to
add a stub entry in a patch release.
2) The difference in behavior only occurs in case of a memory
overflow, so the shit already happened.

Does that help? Or do you want me to explain through a realistic scenario?
What exactly is your worry?
