+  # update also minor versions - reasoning is that:

+  # b) minor version should not contain breaking changes
+  # ignore list is limited to dynamic SDK packages which is only a subset of shared modules
+  # the remaining packages follow the regular dependency update process - reasoning is that:
+  # a) production code is unchanged and minor and patch versions should be backwards compatible
+  # b) the Console is updating their deps in parallel so an up-to-date cluster may be close to our versions
+  # c) shorter ignore list is more readable - note that dependabot does not support yml aliases (yet)
+  # d) the shared modules list changed in time and would require different ignore lists per branch
