Healer DPS is still NOT going to be a requirement in Stormblood. I know people have already cited the interview question Yoshi-P answered on the matter, but to reiterate his last line:

"That being said, and I want you to really reinforce this to your viewers, I firmly believe it shouldn't be mandatory and we DO NOT have the expectation of [healers] to DPS."

I understand why people want healers to contribute to DPS, and I understand sometimes it's frustrating in especially low level content to see a healer set to follow doing nothing. However it's not your job to dictate how they play their class. Kicking a healer for not DPSing can still get you reported for abuse.

Also, as a healer who plays top DPS in MOST dungeons runs: Maybe instead of blaming healers not DPSing for why your runs take so long, you should fix your tank/DPS rotations so they actually do something and speed things up that way.
