I have to admit that I haven't kept up with the discussion today, but
I was also hoping to see some proof. I'm genuinely interested in
seeing if this is something that can help me and the teams I work
with. I was very interested in DbC a long time ago, but never found a
way to make it valuable to me.

I'd like to see a project from PyPI converted to use DbC. This would
make it easy to see the real world difference between an
implementation developed using DbC compared to one that is well
documented, tested and maybe even includes type hints. Toy or
cherry-picked examples don't help me get a feel for it.
