They are completely redundant in terms of gameplay. You only need them to deal with mechanics that were purposely put into the game to make tanks necessary, i.e. un-avoidable damage at levels DPS can't take. Remove those and tanks are not just not mandatory, they are unviable.
Likewise, if all damage was avoidable, healers would only correct mistakes with no other purpose of existing. And that is why we have all kinds of un-avoidable damage. Both of these roles exist solely for their own sake, they deal with mechanics that exist to necessitate them and that is precisely the reason why more mitigation/healing than necessary does not provide a benefit, whereas more damage than necessary does. This is the deeper reason behind the "DPS meta".
And because of that, nearly all bosses and mobs are damage dealers rather than tanks/healers. They wouldn't really work any other way - A pure healer boss that never attacks and only keeps healing himself to full until the timer runs out wouldn't be very engaging. And PvP would also be miles less engaging than it already is if enmity was a thing there. In general, the trinity doesn't work well if the enemy also adheres to it.
Further, they do not need to deal damage for enmity, because enmity is an arbitrary mechanic. In case you have forgotten it: The moves that generate the most enmity are not the most damaging as is, which should be a broad hint that the two are separate. You can also make moves that deal zero damage but give you a truckload of enmity. Other games did that actually, but it was phased out. Not because it doesn't work, but because it wasn't fun. People like dealing damage, tanks included.
Bluntly put: People 'should' be forgetting what you claim they shouldn't forget, because it's untrue. I put it in spoilers, because it's off-topic, tho, and I don't wanna bloat the page unnecessarily.
