ip-precedence for management traffic

Experts, what is the general opinion of using ipp 7 'network control' for management traffic like: telnet ssh snmp ..... The idea is that ipp 0 1 2 3 4 5 are used for user traffic ipp = 6 is used by default by routing protocols like BGP, OSPF, LDP ... this leaves out only ipp 7 for management traffic, on the premise that routing and management should not share the same queue and resources..... Thanks, Luca.
