How about yes.
coutner point: I do far too many dungeons this expansion where I was healing, and regretting it, because the tank was war/pld, so I was just a green dps for the entier dungeon run.
It has been really noticeable now this week too, now that people aren't running around in min ilvl gear anymore, and it will become even worse once the new tome and savage gear drops.
The whole "healers must heal" doesn't work in this game, due to encounter design and never will. more engageing dps option is the most realistic solution for healer boredom.
