On an offline discussion we agreed that we are not doing at this moment, as it is a big change on the Template Engine and how the cache works. I'll be disabling the --version option for the command while this is not implemented.

For the case of not installed package: since we retrieve list of templates from the search cache, we can do it only for the latest version.

• If --version matches the latest, it should be possible to show the list of templates from the search cache
• if --version is not latest, there is no way to do that and template list should not be shown.
