Yeah, but it's not an exact science, any way you slice it.
I just did a quick crunch of yesterday's data from our web proxy logs, and
accesses of URIs based on the FQDN "b.scorecardresearch.com" (a banner ad site,
I believe) had over 570 different combinations of website content categories,
depending on URI. One FQDN, 570 different possible ways one might want to
direct the traffic. DNS-based approaches simply may not have the granularity
necessary to get the job done.
Speaking of web proxies, that should probably be the *first* thing that gets
put into place, if the goal is minimize "disfavored" web traffic from
traversing expensive WAN connections.

I can see the value for services that have FQDNs that resolve to IP addresses
outside of their ASN(s) like Google / YouTube.
