All depends on if you actually want DNSSEC to be deployed or not.
If something like NTA (or some other way to override "obvious" DNSSEC screwups) didn't exist, do you *really* think that Comcast and 184.108.40.206 would be doing DNSSEC validation? Do you remember the fallout from the NASA screwup?
Simply telling your customers "Yes, I know that it worked fine from $competitor, but we do things better here, and so you cannot see "fluffy kitten chasing ball of yarn". It's for your own good, and it also teaches fkittenvideos.com to not suck so much…" doesn't cut it.
