Imagine a DPS fucks up and needs to be raised during a fight, he raises at a VERY BAD TIME, and an AOE is coming out to kill him again, being able to aldo the DPS before the raid damage takes place saves him from dying again.

That is just one example, I can think of a dozen other examples where higher SS would help out with healing.
I don't want to harp on this too much since my goal isn't to gang up on you, but I would just emphasize how extremely miniscule the casting time and GCD reduction benefit is for how much SpS you need to stack and then call attention again to how virtually every encounter in this game is choreographed to an extremely high degree. Besides, the majority of mistakes are either very survivable or very lethal, and casting ~0.1-0.2 seconds faster is probably not going to make the difference in the latter case (if you do react immediately and have a shot at saving the person who screwed up, you're probably going to choose an oGCD tool if you have one up, anyway).

While it's possible to have an oddball situation where that smidge of added SpS makes a positive impact healing-wise, it's exceedingly unlikely. The primary benefit of SpS, as has been discussed in this thread, is for DoT/HoT effects and for chaining hard casts. I don't have a problem with SpS from a DPS perspective, but I maintain that you could strip SCH down to base SpS and be challenged to notice any difference in how you heal, especially if you're anticipating and not healing purely on reaction.
