+// future rules_nodejs release, the runfiles helper won't be required as standard node module
+// resolution works with the linker.

+// We could have left the `bootstrap` attribute in for 1.0 and removed it for 2.0 but since we had
+// an alternate approach that we're using here that isn't going to be broken in the future by the
+// linker being added we decided to pull it for 1.0 so that we have fewer major breaking changes in
