Users testing the v3 beta CLI seem to often forget the new syntax and use old commands:

https://forum.ionicframework.com/t/error-unknown-plugin-ionic-cli-plugin/85483
ALL documentation out there now will use the old commands, probably forever. Using the old syntax shouldn't lead the users into a non-explained error the CLI certainly could anticipate.
Wouldn't it be useful to map the old commands to a helper that outputs an information about the new syntax but also aliases to the new one (or intercepts the request so at least there is no error)?
