Comment 1 for bug 1896659

I agree that it can be difficult to manage and clean-up shared report templates. But, I think the idea behind the shared templates is that anyone with access could use them to run reports. I'm not sure that there is value in sharing if this would not be the case. I also would not advocate allowing templates to be deleted if other users had run reports associated with those templates.

While shared templates can be hard to manage they do, in theory, ensure that all users are getting the same report output and it is easier to update one template than multiple copies of the same template.
