Rust 1.55, cargo rustc --release --verbose --profile dev : error: usage of `--profile` requires `-Z unstable-options`

Problem

This stopped working on 1.55 :
cargo rustc --release --verbose --profile dev
error: usage of --profile requires -Z unstable-options

Works fine on 1,54

Output of cargo version:
cargo 1.55.0 (32da73a 2021-08-23)
release: 1.55.0
commit-hash: 32da73a
commit-date: 2021-08-23

Apologies! I have posted #9898 to fix this. In the meantime, --profile=dev is the default, so one workaround is to not use that option.
