It’s an apt comparison because we see Affliction locks all the time who say “I only want to cast dots. Any time I cast Shadow Bolt, that’s an abomination.” But we want Affliction casting Shadow Bolt. Casting Shadow Bolt doesn’t mean casting nothing but Shadow Bolt. Likewise, we want druids to cast Nourish and Healing Touch and not just keeping Rejuvs on everyone.

Classes can feel different from each other without being so unique that they have nothing in common with each other. If you’re going to invest many hours healing on a druid, it’s more important to us that what you’re doing is dynamic and engaging over the long haul. You’ll notice that a lot more than you will how similar or dissimilar you are to the healer standing next to you. (Source)
