It would be nice to have a flag to cargo publish which publishes all local packages in a DAG fashion.

Non-atomic publish was added in #14433, stabilization is being tracked in #10948

Testing instructions: #1169 (comment)

Notes (edit ehuss):

• publish multiple crates, races with dependencies #9507 would block this
• It would be nice if it supported atomic publishing.
• --dry-run should work correctly (will need to pretend that the previous crates have been published, maybe via patch?) See also Add a dry-run publish API crates.io#1515.
• See New publish API crates-io-cargo-teams#82 for other considerations for a new publish API to better accommodate this.

Blocking issues

• Wrong workspace publication order in the presence of dev-dependencies #15412

Non-blocking issues

• cargo package (and hence cargo publish) verify step is slow from doing a full build #14941
