This seems like a bad idea, I can come up with a number of cases where the priority of a request would better be optimized by a higher level subsystem, rather than a simple prioritization based on the command type.
The original suggestion to provide both head and tail insertion options seems like the obvious solution, short of a full priority queuing system.
