If those free GCDs can be used for dispels, then raid leaders will let the DPS continue to DPS while the healer dispels.
Bind Elemental and Hex aren't huge concerns since adds are not classified as bosses so your miss chance is much lower. If the mob is really dangerous and needs an immediate CC, multiple people will do it just to be safe.
Alternatively, having no hit is can be a really bad thing. My guild, and likely others, used a paladin healer to heal the tank on Steelbreaker for both normal and heroic mode. That same healer was in charge of dispelling fusion punch. Multiple times, our healer had a miss on their dispel and we wiped. RNG determining a boss kill is not fun.
So, what is a happy medium? Blizzard already made it. By changing bosses from 2 shotting tanks to steady moderate damage, there is no immediate need for a dispel or CC. Will there be some bosses that will need immediate dispels/CC? Of course. On those fights, you can make a DPS do it. Otherwise, anyone with a free GCD is a perfectly viable candidate.
