### What needs to get done * Add a warning that `--build-for` is deprecated for `snapcraft remote-build` * Hide `--build-for` from the help text ### Why it needs to get done * To align with the upstream remote build command in Craft Application * To align with rockcraft and charmcraft's remote build commands * It has a significant limitations due to Launchpad's API and forces snapcraft to add many restrictions to valid platform defintions * `--build-for` is planned to be deprecated in Craft Application This is blocked by a migration to Launchpad's new build farm where we will be able to provide proper support for the `--platform` arg in remote builds.
