MXS-2432 Recognize RESET

Browse Source 
RESET QUERY CACHE is reported to be a session command, which will
cause it to be sent to all servers. RESET [MASTER|SLAVE] are
classified as write, which will cause them to be sent to the master.

It could be argued that RESET [MASTER|SLAVE] should cause an error
to be sent to the client.
