PTAL @johanbrandhorst, it seems like a bazel test is not passing but i think it's not something related to this change.

@glerchundi, Yep that is on me. Lemme send a PR to fix Bazel. Sorry about that.

#841 should fix that. If you could please rebase it would be hugely appreciated. Thanks!

@achew22 rebased, lets see :)

Thanks!
