In the Languages gadget (Language Manager add-on), users have the option to duplicate content when creating a new language branch. During this process, the “Duplicate content” dialog presents checkboxes for:

Add all children

Add related content(s)

These options are useful for administrators but pose a risk when used by editors who may not fully understand the implications. For example, an editor in our organization mistakenly duplicated a section with over 800 nodes, resulting in around 500 duplicated blocks. This caused significant manual cleanup and unnecessary content clutter.

Feature Request:

We would like the ability to restrict visibility or access to these options based on user roles, ideally allowing only administrators or users with a specific permission set to see or use these checkboxes.

Benefits:

Prevents accidental large-scale content duplication by non-admin users.

Reduces cleanup effort and risk of content sprawl.

Adds a layer of governance around language branch creation.
