wp-cli for Creating page-template

wp-cli is not a development tool, it is a server admin tool, as such all the scaffold stuff there is…. for lack of better word, unneeded bloat. It is unlikely to reflect best practice, especially if your copy is old.

In the specific case of page templates, there is really nothing worth “scaffolding” the easiest way to create a new page template is to locate one in a theme, copy to a different file name, remove the code (or not, depending how drastic the new template will differ) and edit the template name in the header. Using wp-cli for this will probably take more time.
