No it's not.
People say this about Tanking and DPSing. And have several options that fit it - WAR for Tanks and SMN for DPSers. Before SMN, it was RDM, BRD, and/or DNC.
It's actually been true for most of the game's history that each Role had at least one simple one, and the simple ones were often the most played, but always had adamant fans of its playstyle who didn't want it changed.
EDIT: And as I've told you before, this isn't even limited to FFXIV but tends to be true across MMOs and even into other genres. Most games have an "easy one" if they have a diverse set of options. FFXIV is no different. BRD was the "easy one" for much of the game's history in terms of DPS Jobs. WHM for Healers. Tanks were arguably the Role that didn't have an easy one until WAR drifted into that position, and PLD has somewhat joined it. And if you go look at the Tank forum, you'll see there are some PLD die-hard-opposed-to-6.3 people, but also a lot of people touting it as generally good and/or a step in the right direction.
A very common question on Reddit for FFXIV is "I want to pick up X role - which Job is the easy/easiest one?"
This isn't new or unique to Healers in any way. The only thing that's relatively new is people insisting there shouldn't be one.
