Looks good.
For the record: We discussed this change at the ROS 2 meeting, and decided to grant an exception to the core freeze for Galactic due in part to the limited scope of downstream usage and the return to previously established behavior that this change enables.

@jacobperron its my plan to release nav2 shortly. I'm going to assume from the 2 approvals here that this is on its way so that if I merge the complementary Nav2 PR, we should be good to go? |

@SteveMacenski That's right, we should go good to go. |

Backport #1673 to Galactic.
I've released this change into Rolling and haven't noticed any regressions. The only code I found that this affects is in navigation2 and I've got a patch there: ros-navigation/navigation2#2347
