Is it fair to say that DNS would be the prime reason for anycast addresses

Eg: counting how many global BGP prefixes are "anycast" due to their
properties,
such as availability at widely disperse nework locations without actual transit
indication in the AS path attributes (or the like, i am not a BGP expert, i am
just guessing how they could be recognized).
It may be on the global Internet, but there miight be other uses.
Common? Ridiculously so, for at least 20 years.
Well known examples? CDNs, as you already mentioned. E.g. LLNW.
Thanks for the example. Any non-CDN examples for localized information ?
An early paper:

c) Any example in which the DNS servers utilizing a single shared
IP address (anycast address) are run by different operators ? Any
documents describing this ? (RFC3258 seems to focus on single operator
anycast group of DNS servers.
How about the root servers?
Plus ISC has a tech note:

There might be something @ DNS-OARC that covers thisin their back catalog
of presentations.
