You can gzip it and deploy it now. Hopefully, dfx will do this for us soon? Maybe? Please?

@roman-kashitsyn shared this concern about doing it on behalf of users.

New and Improved Rust CDK: First-class support for Rust Canister Development

It depends on whether you care about build reproducibility. The replica exposes the SHA256 hash of the compressed module (it stores exactly the bytes that you’ve sent), and compression is not deterministic in general. I would not want automatic compression by DFX for canisters I work on: we use a custom build procedure anyways; we could just as well add a compression step there (1 extra line).

Perhaps an entry in dfx.json to easily enable or disable it (depending on the default) would be a good compromise.
