The cap, really, is shared between both and probably therefore should be thought of per a shared term --say, sustain (how much HP restoration or preservation can be thrown at something in a given moment to actually extend their life), which wouldn't care of whether that includes a increase to maximum eHP unless the latter actually does something extra.
In either case, I think it comes down to what we've all said earlier: barrier healers just heal too much, to the point that there is no real/additional cost in throwing up GCD mitigation (be it percentile or flat) for things that don't need their max eHP increase.
And if we want more room to diversify forms of sustain, well... we probably need more damage intake (especially, in excess of our oGCD means of dealing with it), sadly.
