Thanks so much for opening this! I think this is the right solution. I had one suggestion, and you'll need to fix the linter errors and sign the CLA for us to merge it. 😄

Does this need a changeset? And if so, would you give this a minor version bump because of the potential for snapshot changes?

[devongovett]

Thanks! Yes, we will release this as a minor. We will be doing some testing in the next few days and probably releasing early next week. We'll take care of the version bumps and release notes. In the meantime, you're welcome to use our nightly releases.
