People actually liked Healing

Say what you will about the changes in S9, the usual videos of "how to climb" and whatever else.

A lot of people came to Overwatch and stayed because instead of just having another Deathmatch game that a lot of people are going to cheat to win at, Support was popular because those players could HEAL and NOT be just as responsible for doing the job of Dmg. Like it or don't, but if these changes are the future, then maybe it's time to redefine what the "support" role really is and just move it away from healing completely.

...and lose the players that liked contributing the group when they aren't great at twitchy aiming or dmg in general.
