This requires consumers to have Swift 5.6, why would we place that restriction on them?

Testing these changes as local packages fixed the problems seen in the issue. Not sure what the difference is, but the version we were using was a handful of months behind. The release page mentions vending the internal parser library as a binary framework on macOS, but 🤷🏻.

Ah, yeah I didn't consider that.

With the understanding that this change took us from "it doesn't work" to "it works" I think accepting Swift 5.6 makes sense.
