Hide Copied New Language Tree Pages Until Published

Permalink
When copying a large / deep language tree from one language to a new language the new pages are instantly "published" and available to the public view (searches, auto-nav, page lists.)

Browsing previous forum posts has revealed solutions utilizing the "exclude from" custom attributes:

Exclude from Nav
Exclude from Page List
Exclude from Search Index
Exclude from sitemap.xml

This would be extremely tedious (and error prone) on a language tree with an excess of 100 pages. The inverse task to "publish" would be equally as tedious.

A newly created page is not "published" by default. What would it take to make a new language's language tree copy also not published by default?

Other suggestions I have found involve manipulation of the page permissions which is something for which we'd rather not expose to (or confuse) lower privileged editors.
