A fine point, admittedly, and something that's probably never actually pursued. But if you launched a nationwide campaign to get everyone to use, say, the Level3 DNS servers, they might come after you!

I used to work at Level(3). "could do so" is true, but "could easily do so" is probably not. Making a list of all the customer addresses can be difficult. Unlike residential ISPs, Level(3) customers don't always get addresses from the ISP's address blocks. Many of Level(3)'s customers are large businesses and smaller ISPs, who have their own address blocks. When I worked there we had no central list of all of them, and I'll bet this hasn't changed.
And even if the list can be generated, it would be huge. I'm not sure if BIND's access list checking is designed to handle enormous lists efficiently, so this could be a severe performance problem. So rather than try to configure an inclusive ACL, we dealt with abuse on a case-by-case basis when necessary.

In any event, it's not a marriage - you can plug in those servers and try them for a while. You can always go back to the automatic assignments from Comcast.
