I think the community is willing to accept certain things being "Imbalanced" with certain caveats. For example:
DK's have no "block" mechanic
DK's have no AP debuff
Lets say for the sake of argument, that they were in a 10 man, that was thrown together, that didn't have a ret paladin, warrior, or feral druid or warlock. (I have been in such a 10 man on my DK pre-nerf). There would be no AP debuff on the boss. A DK, properly specced, geared, etc... would be at an obvious disadvantage. The disadvantage can be overcome with skill, but the disadvantage exists.
I think the community would be "ok" with DK's having an armor advantage to compensate for that. Not a game changing (30% less damage taken) amount, but enough to at least split the difference. That would give them a small advantage during fights where the AP debuff was present, but not cripple them when it wasn't.
Would this be "balanced?" No. Would the community completely rage about it, if this was the only advantage a DK tank? As long as it wasn't as powerful a difference as AD, I don't think it would be enough to write home about.
TLDR: The community will accept imbalances as long as they are not GLARING imbalances.
