My speculation is that they don't want to promote the idea of any playstyle that might make the game seem hardcore. This isn't to say that dealing damage while healing is some kind of hardcore activity, but we have to remember that the bar for "you must be X tall to ride" this proverbial theme park is set around 4 feet. This is a business, and perception is king.
Getting people to play support in party-oriented games can be challenging to begin with because of the perception of responsibility. If it's not that, it's that PvE content with a pure healing model is usually boring as hell, and very few players are dedicated enough to their role to stick it out until end game. If the dev team stays quiet on issues of playstyle, they can let players sort out their own meta and not risk directly alienating anyone.
In my perception, the ideal situation is that new healers learn their role as they level up and (hopefully) read the objectives and start to piece together a playstyle that meshes well with all parties. It's the "healing-only" healers who get stuck in a rut, whether it's because they somehow missed the memo while leveling that DPS helps or because they've decided to boycott this interpretation of the Healer Role. In the former case I would like to help those players learn that they can play bigger and better, that they can be real powerhouses that help their parties; in the latter case I would like those players to understand that their choice, while pleasing their sensibilities, is selfish when measured against the fact that other players have to carry the weight of that choice.
