Unique URI in all defined routes

[lostika86]

Does Statamic validates URI uniqueness against routes, which are defined in routes/web.php?

Goal: disable entry creation with slug blog.

Logic:
blog slug is already defined in routes/web.php as Route::statamic('blog','blog_items_listing.antlers.html',['layout' => 'layout_custom_blog']);
If user creates an entry with blog slug, and UniqueEntryValidation is defined, statamic saves it with slug blog.

Is there any solution how to disallow save URIs which are defined globally?

Make a blank page entry where the URL is /blog and set the custom layout/template on that:

layout: layout_custom_blog
template: blog_items_listing

The UniqueEntryValidation rule only cares about the URLs of other entries, it doesn't take custom routes into consideration.

Yes, it can be a solution. Honestly, I do not want to create entry for this.
example: I have collection for blog entries, which I plan to relate to '/blog', but I want to eliminate deleting '/blog' - this is the reason why I do not want to create entry for /blog
