Well, yes. WHM still has major issues, but the only reason people quieted down about it is because SCH actually got hit out of nowhere with nonsensical nerfs, to the point where they're now getting shut out of raid groups almost as hard as WHM did during the last few months of Alexander. And the other healer being in a bad spot somehow automatically means that the other healer with questionable job identity has good long-term design.
I guarantee you the whining about Plenary Indulgence would be 100x louder if SCH was still guaranteed a raid spot like it was in HW.
