That was so fast 😂
Thank you also for the cleanup!!
Note that this will need a version bump (prod version) so we can release it and get it into core. And then a core PR that bumps to that version.

@courtneyholcomb Are there any other validation tasks? Would it make sense to wait for some of those to be done then we can batch all those up and release it once?

@WilliamDee
Good call, yeah I think there are! Can you put up a task to make sure we don't forget?
