I don't exactly agree with the demo warlock comparison because if there is one thing I believe about this team, is that they want you to pick any standard job within a given role that appeals to you for whatever content and not feel like you are holding your team back.

Their problem is that the team doesn't make healers appealing to a large sector of veteran healers. Maybe they don't know how? Maybe there is a conflict with other design goals they deem more important? I don't know because they don't talk healing much...
