Validation on prototype page

For pages created from the Channel Manager using a template (eg. a prototype page with one container that has specific item containers components in it), validations that will alert the webmaster that he deleted (by mistake let’s say) an item container ( ‘DELETE COMPONENT’ button) would be needed.

Another possibility would be to disable ‘DELETE COMPONENT’ button .

We need this because we want the webmasters to have a page skeleton that will tell them which are the minimum hst:containeritemcomponent that should fill a page (hst:containercomponent). These prefilled containeritemcomponents contain sensitive data that I page would need to proper function (eg, a form) and deleting this by mistake would break pages and flows.

Before making this task, I have searched if something similar exists, but I could not find it.

Thank you in advance
