Mostly as a server requirement.

Unless the requirement on servers is MUST NOT, it is not possible to add a  
requirement for clients. Although, if there is also text saying that  
clients MAY refuse cookies with names starting with $, that would  
certainly emphasize the point (and would be useful for clients supporting  
RFC 2965 or the proposed $Origin attribute).

RFC 2109 also says about name

       NAMEs that begin with $ are reserved for
       other uses and must not be used by applications.

Admittedly it is only only using small letters, but maybe it is time to  
strengthen that language?
