Yeah, I'm totally cool with going with `=`, but I will point out one snag.
What about users with existing stellar enrichments using `:=`, would we provide
a migration path beyond saying, "Hey, move your stuff over" in the Upgrading
docs?
Migration, sadly sometimes, is also part of user experience. :)---
