I think they'll likely get a small change in that the unhappiness doesn't take effect until the city grows a bit.
If a city has to have, say, 4 pop before you get the doubled unhappiness, it would allow India to expand and avoid growth to found cities, as well as delay unhappiness from unchecked city growth, AND really dampen the penalty.
Wouldn't that be a just a bit antithetical to the very name of the UA? Parameters that would have you curb population growth on a UA named Population Growth wouldn't make much sense.
