What healing do you mean here? If you mean Cleric's healing, then this may be true if you are coming from 4e where AFAIK there are plenty of options to heal yourself automatically and there are many classes which can heal others.
But if you are coming from any earlier edition, 5e has MORE healing than ever out-of-combat, so a healing cleric is certainly not more needed than it was before and possibly less.
I don't agree with the notion that a cleric has ever been needed in any edition for healing after combat. People want healers for their in combat healing so that their characters don't die ignominious deaths; killing the dragon before sundown is just a bonus.
But I don't think clerics are more needed in 5e. I think the perception that they are needed is about the same as in all other editions...people still don't want their characters to die.
I do like the Herbalist Specialist; it helps in smaller parties or when no one wants to play a healing class but wants some healing ability. Options like that are nice. But then they also put in the Divine Magic Specialist, allowing clerics to become even better healers. Ok Bobby, not only do we want you to play a cleric, you need to choose the Divine Magic Specialist option to be an even better Healbot!
