Hi Jan, I do not have a list either, but I have counted resolvers on RIPE Atlas for which the o-o.myaddr.l.google.com. TXT query reports a ECS value.
https://dnsthought.nlnetlabs.nl/does_ecs/#top_auth_asns Besides Google and OpenDNS, VeriSign is showing up there quiet prominently too. -- Willem PS. Other ASes - that do not do ECS 0 spill over a bit when they are part of resolvers that forward to multiple other resolvers, of which one is supporting ECS. Hence a portion of false positives in the graphs.
