I don't know if that's the right type of attitude to have about a core problem that really seems to be about people simply losing enjoyment; at least I think that's what's going on here.
I know I'm out of my depth in this conversation, but I do know what I'm capable of, and I'm not a gamer who has the multitasking proficiencies a healer requires. I know this because I've tried it before years ago in World of Warcraft, and I was terrible at it.
A person should play what they enjoy and have fun with, not what they think the game or others require of them, and someone who is having fun with their job in FFXIV is very likely going to be good at it.
Healing does not look fun to me, it looks like busy work, it looks stressful, and I don't pay 36 bucks(sub+all retainers+premium app) a month on this game to stress myself out.
People who heal in this game are obviously good at it, which means they are also enjoying it, otherwise they wouldn't put themselves through that type of stress and anxiety, and i try to always keep this in mind when i'm in a dungeon, i always try to stay out of damage as much as possible, i try to stay within the healers range as much as possible, and i try my best to always give them commendations. I do what I can to not take for granted the effort others are putting into their duties.
So I don't think looking for others to experience the unique situations, anxieties and hurdles of another is going to communicate whatever 'this' whole thread discussion is really about, which... I'm not sure it's even going to materialize in-game, and if it does, i'm not sure i'll see it, but i have no desire to be dismissive of it, i just don't know what this is really going to accomplish other than annoy people.
