The simpler media website CMS
I'm working on a theme that doesn't respect most of the default theme options, like rows/columns, thumb size, that sort of thing. I have a very good reason for that, don't worry (and I'm happy to take on the argument, but perhaps not here & now).
So I want to remove or hide them in the options for my theme, as they will only be confusing. They won't do anything, and I certainly don't want to raise false expectations from people who might use my theme, when I release it.
