Its not the DEF per se, its how complex things have become. I wouldn't delete it either. My EGR is deleted on my 6.0 b/c it was a known failure point.
I think Ford mostly has it right with the 6.7, but unless I needed a diesel to haul 10-12k regularly I wouldn't buy a new one, just too much money and complexity.
