It would be great for it to be possible to delete the "checkout" and "order confirmation" pages if you decide you no longer want a website to be an ecommerce website.
There's already a years-long discussion about it in forums, but I thought I would move it here to make it official.
I made a website ecommerce and later decided against it, and somehow the checkout page is still getting some views. I think it looks pretty bad to have a random unused page like that.
There doesn't seem to be a workaround besides creating an entire new project and moving pages to it, which is pretty time-consuming, especially if you have a CMS website.
