Well it's as simple as having high-priority traffic protected under DDoS on MX platform (to have behaviour consistent with PTX or old T4k). 
And yes there is a light at the end of the tunnel, since 17.2R1 all MX cards since mpc2-ng till mpc9 will have tuneable pre-classifier, so you can change the incorrect defaults.

Though I think you'd need to ask for this on MX10003 MPCs.
