I think this is already planned, but I'm opening an issue so that it can be tracked.

Adding globs support will:

• reduce a lot of user mistakes (like forgetting to add new packages to the workspace)
• make migrations from the current melos version to the future melos version where packages are instead defined in the workspace much easier, since their current definitions could just be moved from melos.yaml to the workspace config file
