I didn't mean to sound snippy! I too have NN4 for testing, but using it day-to-day... yeesh.
I take your point about the potential loss of revenue, but since on my site it would probably see me leaving 10 cents or so on the table, I'm not going to sweat it. I'm fed up with tweaking for NN4. So call me a standards nazi ;o)
