Yes, the present low healing requirements mean that we'd still encounter a problem of (roughly) the same type even if we reduced tank's self-sustain, since even Healers' free healing would still be great enough to make GCD healing feel excessive. However, the party would still, very literally, have less excessive healing (speaking in flat terms), if tank sustain was reduced, just as it would if Healers' free (oGCD) healing were reduced.
It would be, imo, a poor approach to handling the situation, but it wouldn't be irrelevant, nor would there be no benefit to healers' place in content resulting from the expense to tanks (even if it'd arguably not be a net positive for the game, and an altogether unnecessary cost regardless).
