It's not that it's imperfect, it's that it's insignificant.

If the proposal had no costs, it would obviously be worth pursuing.

But it's a historically disruptive proposal. For changes on that scale, we should be targeting significant fixes. 10% is just nibbling at the edge of the problem --- to put it another way, if the cost savings is 10%, then a few years after the change was enacted, we'd be right back where we are now.

You can't iterate on restructuring the economy; it's not a PHP program. You can iterate on incremental fixes, but that's not what M4A is.
