Which is utterly inexcusable, just because you support some new things in
the backend, does not mean you should expose completely new abstraction
model to the frontend.

What you configure in EVC should be configurable just as well in
subinterface. With the difference that your existing config parsers would
work and your existing SNMP graphing would work etc.

I'm not even proponent of backward compatibility, if some benefits can be
gained by making things in a new way, I'm all for breaking stuff. But if
there is some benefit at all in EVC, I've not yet seen it, and I'd love to
be corrected.
