It seems that I will have to learn to use PYTHONNODEBUGRANGES=1 and 
-Xno_debug_ranges. I close the issue.

Sound like you likely want to use the environment variable to deactivate the 
extra information ;)

Special is not uncommon, is just some different behaviour rather than the 
default one. I am not arguing that is a rare scenario, I am arguing that is a 
special case.

Ah, I thaught that the PEP was implemented in 3.10, I didn't notice that it's a 
new feature of Python 3.11 :-)

In my example, there are 6 frames. The indicators cover the whole line of 3 
frames: 50%. It's a common case, it's not special.

Python tracebacks are already very verbose: a single exception can easily take 
20-30 lines. It's worse for chained exceptions. Python 3.11 makes it worse: up 
to 1.5x longer.
