Add the cost and inconvience of heat sinks.  I built a FWD, 9100v no-load 
8171 supply with 3A diodes.  It is still working, 19-years later.

There is bound to be some piv variation.  To find out what's what, one 
needs a high-pot. // Without any "voltage sharing strategy", there is 
Always equal reverse current in each diode.  Some things are best left 
alone.
