After merging https://review.openstack.org/#/c/254929/ and https://review.openstack.org/#/c/254201/ size of response for bundle.js reduced from 3.2MB to 377 KB. Enabling babel-runtime actually increased the size slightly, so we decided not to enable it.
I think this issue should be considered as fixed.
