An --empty-checksums option?

[julian-klode]

In Ubuntu, we remove the checksums for files from vendored crates, such that we can then ship patches for those crates without having to patch the checksums too! This feels like something I'd like to shove here if that feels right?

Sure, SGTM.

That said, presumably a tool could be handled such that it only dropped the checksums out when going to patch a crate? But yeah, a bit annoying I guess, and the cargo checksumming isn't usually adding more integrity than the outer buildsystem provides in most production use cases.
