LGTM. I wonder if dependabot is smart enough to consider recursive rules like… a middy major version ignore for all of them.

We did not have ignore block yesterday and we had the same behaviour: no upgrades for root, but upgrades for examples projects. The default versioning-strategy is set to auto which tries to guess if it should upgrade or not, and also ignore the package.json version cap.

auto | Try to differentiate between apps and libraries. Use increase for apps and widen for libraries.

My assumption is that dependabot treats examples as app and tries to widen the version. See more under versioning-strategy docs
