### What needs to get done Add a deprecation notice for `snapcraft pack <directory>` and recommend using `snap pack <directory>`. ### Why it needs to get done So that `snapcraft pack <directory>` can be removed in an upcoming major snapcraft release. This command is being removed because: * it does not support packing components * it is a poor UX because it has a different behavior than `snapcraft pack` and does not execute the craft-parts lifecycle
