The thing is (I don't know a lot about NM so I may say crap), “online”
status is global, not per-interface. So either you're online, either
you're not. The grey area where you're online on an interface not
managed by NM is impossible to manage. So maybe NM shouldn't manage it,
but if it does, it has to do it globally. If you disagree, then don't
use NM. (especially since “online” is fuzzy anyway, what if interface is
up but you're on a non-routed network? what if you're routed but
filtered?).

Afaict, NM works fine for simple cases. For the others, just do stuff
manually. But override offline/online status in evo won't be enough, it
should be handled in NM anyway.
