Of course that's one of the ways, I suppose :) chflags is useful but root limitation feature is not useful for common users I suppose. With our expansion, common users can check files or directories on self-responsibility. And unusual commands like chflags I just suppose are no much point in this case. What is important is that adding mistake protecting functions into common commands like rm(1) itself. Of course I respect your opinions and all comments are welcome :) I have no intention to add our expansion to src tree. It just is a little patch for folks who have a interest of it.
