What privilege is needed to create list templates?

I got a guy who wants to make templates from his lists.  He gets denied access.  My research turns up the suggestion of adding him as designer to the List Template Gallery (_catalogs/lt/Forms/AllItems.aspx).  Well that library inherits from a parent.

• I don't know what damage I would cause if I stop inheritance
• When I navigate to the parent I have no idea where I am or to what I am granting him privilege
• If I stop inheritance, add him and turn inheritance back on his privilege is eliminted
• When will Microsoft learn that you can't provide security when limited to a hierarchical structure?

What can I do?
