At least nice-to-have if not blocking tasks before flipping the repo public. Constraints that make this smaller:

• We'll only be publishing the Smithy build plugin (codegen/smithy-dafny-codegen) and not the CLI, which we hope to deprecate anyway.
• We'll only be claiming support for Java initially.
• We'll be very clear about what what shapes and features are not yet supported (and #185 is particularly critical for that)
• We'll be publishing a 0.x version, just like all other smithy-<lang> projects.
