Completely un true.  JunOS can rate limit based on a lot of things.  Some 
methods are more accurate than others and in some chassis the fact that 
there are multiple FEBs complicates the actual implementation (packets are 
scattered across FEBs into J-Cells as they come in) but there's nothing 
anywhere that I've ever seen that says 'interface must be HDX'.

You can rate limit an interface, a sub-int (802.1q vlan if you will), 
police based on port, port protocol, dest/src pairs of various types, etc, 
it's VERY flexible.
