Honestly, a "restricted shell" is usually a pitiful thing that would be a joke, except it's not even funny. It's what people tried to use for security back in like 1990 when nobody had a clue about security. Typically the users find a way out of the "restricted shell" within a couple hours by trying shell escapes in every command available to them (man page viewer, text editor, etc.) until one of them works. I have no idea what the POSIX standard has to do with your question, though.
