Well, in means of full nat - yes. I have no statistics of how people use 
nf_nat/xt_RAWNAT, but in my tasks I have a lot of packets that do not need DPI.
xt_RAWNAT works great and nf_nat led to packet loss. It probably was because
of main conntrack lock. Yes, I read it was removed not long ago, and haven't 
tested it since then, but anyway I do not want to use such a monster just to 
change 2-3 fields of packet. Just an use case, decision is up to you =).
