I don't personally care either way as I'm a casual player, but what would adding an official damage meter even change? People who do high-end content already have other ways of monitoring their DPS, so they don't really need it. And if you think casuals seeing how bad they are would encourage them to become better, you're sadly mistaken. If bad casuals were interested in improving, there's nothing stopping them; there are plenty of guides out there to help one become a better player. If they cared, they would have consulted them long ago. Seeing how bad their numbers are won't change anything.

Again, I don't care either way. I'm mostly just confused, because the damage meters are already out there, and whether they're official or not won't change a thing. It seems to me that really what some people want is for casuals to be confronted with their low numbers and then feel bad about them. I'm not going to judge anyone if that's what they want, but if that's the case I wish they would just come out and say it, since I don't really think anyone is under the delusion that "a HEALER's role is to HEAL >!!!" Andy over here is magically going to become competent just because the game told him he doesn't know how to press his buttons.
