But this doesn't show luck of interoperability? An Ethereum resolver should be able to accommodate all of them, may be with some pieces of configuration for each of them

Check institutional login here https://ieeexplore.ieee.org/Xplore/home.jsp You can login using the user management system of over 100 universities. Each university uses its own type of "registry" and you need only one resolver (may be with a configuration file with over 100 entries, but still).

Of course. I also believe that in the long run things will converge, for example when we have the DID resolution protocol (https://w3c-ccg.github.io/did-resolution/) or with SIOP. So, IMHO saying that "we are targeting interoperability and convergence but we are missing some parts" is an honest response to Mozilla's and others comment. But Evernym's blog post appears to me like saying "we already have it and you are stupid you didn't read the specifications". 

Best,
Nikos
