Well my first answer to that would be that GSLB scales down a lot further
than anycast.
And my first question would be what would the load on the global routing
system if a couple of thousand (say) extra sites started using anycast for
their content?
Each would have their own AS (perhaps reused from elsewher in the
company) and a small network or two. Routes would be added and withdrawn
regularly and various "stupid BGP tricks" attempted with communitees and
prefixes.
I heard some anti-spam people use DNS to distribute big databases of
information. I bet Vixie would have nasty things to say to the guy who
first thought that up.
