+# chrismo: to best leave existing behavior alone, there's no difference at all between
+# `bundle update` and `bundle update --major` - and so the whole new code path for doing the `--patch`
+# and `--minor` handling is completely skipped when `--major` is provided. Obviously, this is
+# the source of the inconsistency. I think with some work on a --conservative flag, we can get some
+# better stuff.
