You may be correct. The subject suggests TLD servers and their upstreams block EDNS(1) (was this a considered choice or an implementation artifact) and there has been a reduction in blocking at the server level. Unclear if this is a deliberate choice or an upgrade artifact that the server admins or the ISP upstreams have made an explicit choice to enable EDNS(unknown) processing at the server.
